SAMSON control valvesSeries 240, 250 and 280 Control Valves include pneumaticand electric globe valves, three-way valves, and angle valves.Their application range covers control tasks in process engi-neering and industrial applications as well as in supply andpower plant engineering. The modular system allows easyretrofitting and servicing.The control valves consist of the valve and the actuator. Theycan be equipped with pneumatic, electric, electrohydraulic, orhand-operated actuators. For controlling purposes and travelindication, accessories such as positioners, limit switches andsolenoid valves can either be attached directly (see page 2and Information Sheet T 8350 EN) or according toIEC 60534-6 (NAMUR rib).The valve bodies are available in cast iron, spheroidal graphiteiron, cast steel, cast stainless or cold-resisting steel, forged steelor forged stainless steel as well as in special materials. All partsof the valve and the pneumatic actuator housing in the com-pletely corrosion-resistant version are made of stainless steel.Refer to the associated data sheets for details.

Series 240Series 240 Control Valves are available in nominal sizes rang-ing from DN 15 to DN 300 (NPS ½ to 12) and up to a nominalpressure PN 40 (Class 300).Control valves in the standard version are suitable for tempera-ture ranges between –10 and +220 °C (15 and 430 °F). An in-sulating section allows the temperature range to be extended to–200 and +450 °C (–325 and +840 °F).The plug stem is sealed either by a self-adjusting PTFE V-ringpacking or an adjustable packing. To meet stricter emissionscontrol requirements, a stainless steel bellows is used.The Type 3241 Control Valve can be equipped with a heatingjacket that may also include the bellows.

Series 250Series 250 Control Valves are used when large nominal sizesand/or high pressures are involved in process engineering,power plant or supply engineering.In addition to globe, three-way and angle valves, four-flangedvalve bodies with bottom plug stem guides, and valves with ax-ial multi-stage throttling plugs, customized valve constructionsto meet customer specifications can be engineered as well.The valves are manufactured in nominal sizes from DN 15 toDN 500 (NPS ½ to 16) and for nominal pressures between PN16 and PN 400 (Class 150 to 2500).The standard versions of these control valves are suitable fortemperatures ranges between –10 and +220 °C (15 and430 °F). This temperature range can, however, be extended byusing an adjustable high-temperature packing to a temperaturerange between –10 and +350 °C (15 and 660 °F) and by usinga bellows seal or an insulating section to a temperature rangebetween –200 and +500 °C (–325 and +930 °F).

Welland & Tuxhorn valvesThe Type RVG Pneumatic Control Valve from Welland &Tuxhorn is used in power plants and in the petrochemical indus-try to control feedwater and other liquids. The valves are manu-factured with globe-pattern and angle-pattern bodies in nomi-nal sizes DN 25 to DN 150 (NPS 1 to 6) with nominal pressuresPN 16 to PN 400 (ANSI Class 150 to 2500).

Series 280 and W&TSeries 280 Steam-converting Valves are used to reduce both thesteam pressure and steam temperature to optimize plant opera-tion and heat efficiency in process plants, for example, in refin-eries, food and beverage, tobacco or pulp and paper indus-tries.Steam-converting valves are based on Series 250 Valves fittedwith a flow divider St III and an additional spray water connec-tion. They are available in nominal sizes ranging from DN 50to DN 400 (NPS 1 to 16), with nominal pressures of PN 16 toPN 400 (Class 150 to 2500) and for temperatures up to500 °C (930 °F).The Type DUV-C3 Steam-converting Valve from Welland &Tuxhorn is designed for high-pressure ranges and can be engi-neered with varying inlet and outlet sizes. The inlet nominalsizes range from DN 80 to DN 500 and the outlet nominal sizesfrom DN 100 to DN 1600.Large amounts of spray water can be injected thanks to the inte-grated atomizing steam cooler. The valve can be operated in awide load range.

Valves for special applicationsThese valves have been developed for special requirements in-cluding cryogenic valves, valves for food processing, dia-phragm control valves and micro-flow control valves.

Control valve details

Valve bodies and stylesThe valve body, valve bonnet and, in some cases, the bottomflange are subject to internal stress caused by the process me-dium flowing through the valve. Consequently, the valves mustbe designed to be sufficiently resistant to mechanical and chem-ical stress.Under the influence of the operating temperature, the materialstrength changes. This behavior can be improved by combiningcertain alloys. For this reason, heat-resisting materials are usedat high temperatures ( e.g. according to DIN EN 10213-1) andcold-resisting materials are used for cryogenic service. The ma-terials table on page and the AD Specification Sheet W 10provide a summary.

Globe valve (T 8015 EN, T 8060 EN)Globe valves allow easy installation in straight pipelines. Fornominal pressures up to PN 40 and nominal sizes up toDN 300, three-flanged bodies of the Series 240 are mainlyused. The plug stem is guided in the valve bonnet, and theV-port plug in the screwed-in seat.The ports of the V-port plug are asymmetric in order to suppressany oscillations.

To handle higher load levels and when larger seat diametersare used, the Type 3254 Globe Valve of the Series 250 is pro-vided with an additional plug stem guide in the bottom flange.

Three-way valve (T 8026 EN)Three-way valves are used for mixing or flow-diverting service.

The mode of operation depends on how the two plugs are ar-ranged. The direction of flow is indicated by arrows.

Angle valve (T 8065 EN)Angle valves are ideally installed when a vertical pipeline and ahorizontal pipeline need to be connected. The process mediumis only diverted once. Angle valves allow the condensate to beoptimally treated, and are practically entirely self draining.In case the process medium is in the flow-to-close direction,wear in the valve outlet can be reduced by the use of ananti-wear sleeve.For process media containing solids, the outlet of the Type 3256Control Valves can additionally be fitted with a ceramicwear-resistant pipe.

Cryogenic valve (T 8093 EN)Plants that produce liquefied, cryogenic air separation gases,often use vacuum-insulated pipelines to prevent environmentalheat being transferred to the medium. The control valves can beintegrated in the vacuum jacket by means of a connectingflange. The valve is designed to widely prevent thermal conduc-tion to the effect that the stem remains free of ice. A bellows sealserves as the primary sealing.The jacketed pipeline is evacuated of air and sealed off after in-stallation of the components. The cryogenic extension bonnet ofthe control valve is often welded to the jacketed pipeline via aflange, meaning considerable work would be involved toremove the valve from the pipeline. However, to make mainte-nance possible, the internal parts can be accessed via the cryo-genic extension bonnet without having to remove the valve fromthe pipeline.

Valve for food processing (T 8048 EN, T 8097 EN)Valves for food processing are angle valves made of stainlesssteel. The internal surfaces exposed to the process medium aremachined to a fine finish or polished. The valve bodies areself-draining and can be cleaned (CIP) or sterilized (SIP) withouthaving to be disassembled. The stem of Type 3249 is sealed bya special diaphragm, preventing bacteria from being trapped.

The Type 3347 Control Valve is available with welding ends, athreaded or a clamp connection according to ISO 2852, andwith a steam line connection if higher purity requirements are tobe met.

Diaphragm valve (T 8031 EN)For viscous or corrosive media possibly containing solids, dia-phragm control valves that are free of dead space and withoutstuffing boxes are an economical solution. The diaphragm maybe made of rubber, nitrile, butyl or PTFE. The valve body mayadditionally be lined with rubber or PTFE.

On-off valve (T 8039 EN)The valve for on-off service is used for tight shutoff of liquids,non-flammable gases and steam. As the valve plug is equippedwith both a metal sealing and a soft sealing, the leakage flowrate class VI is achieved.

Micro-flow valve (T 8091 EN)Micro-flow valves are used for very low flow rates (KV coeffi-cients <1.6 to 10–5 m3/h).The parts exposed to the process medium are made of stainlesssteel 1.4571. All valve parts are made of semi-finished prod-ucts. As a result, special materials can be used in a particularlycost-effective manner, and the valve covers a wide range of ap-plications.

Steam-converting valve (T 8251/4 EN)Steam-converting valves are used to reduce the steam pressureand the steam temperature simultaneously. A connecting pipesupplies the spray water to the flow divider St III. At its innerwall, the spray water comes into contact with the steam flow.The steam flow and the entrained water are mixed in the narrowwire mesh of the flow divider. As the supplied spray water doesnot come into contact with the valve body, neither erosion northermal shock occur. The flow divider ensures low-noise andlow-vibration operation.

Valve bonnetsThe valve bonnet closes the valve at the top and provides roomfor the stuffing box and the plug stem guide. The valve bonnetand the yoke of Series 240 Valves are incorporated in onepiece. The valve bonnet and the yoke of Series 250 and 280Valves are bolted together. The NAMUR rib standardized inIEC 60534-6 located on the yoke allows easy, standardized at-tachment of a positioner or other accessories. The valve bonnetis a pressure-bearing part that is exposed to the process me-dium, therefore its material is subject to the same design re-quirements as the valve body.

PackingThe plug stem is sealed by the packing. Versions with bellowsseal or insulating section or when the packing functions as abackup packing use the standard packing.The temperature range of the standard packing is between –10and 220 °C and can be extended when an insulating section isfitted on the valve bonnet.

Other packings can be installed for special applications.

Steam line connectionThe Type 3347 Control Valve can be provided with a valvebonnet including a steam line connection to meet therequirements regarding purity in the food processing andpharmaceutical industries. Steam or a sterilizing liquid flushesthe plug stem between the two PTFE V-ring packings to preventbacteria from being trapped.

Seat and plug trimsThe design of the seat and the plug determines the KVS coeffi-cient and the characteristic as well as the seat leakage rate of avalve. The drawings show seat-guided V-port plugs with asym-metric ports with metal sealing and soft sealing.

The seat, plug, and plug stem are made of stainless steel. Insome cases, the trim elements are subject to high stress due tohigh differential pressures, cavitation, flashing, or in caseswhere the process media contains solids. In order to increasethe service life, seats and plugs with metal sealing can be pro-vided with a Stellite hard facing, and plugs up to DN 100 canbe made of solid Stellite.The seats are screwed into place, allowing them to be easily ex-changed. They may also be made of other materials.

Metal sealing Soft sealing


Seat leakage rateThe seat leakage rate is determined according to DIN EN 1349which specifies the maximum amount of the test processmedium (gas or water) that may flow through the closed controlvalve under test conditions.For special applications (e.g. using Type 3241-Gas orType 3241-Oil) or with shut-off valves (Type 3351), a highleakage rate class can be achieved by using a lapped-in metalor a soft sealing.

Pressure balancingIf the actuator force is not sufficient to handle the differentialpressure, pressure-balanced plugs are a good solution. Theplug is designed to function as a piston. The upstream pressurep1 is transferred to the back of the plug via a borehole in thebottom of the plug. The forces acting on the plug are compen-sated for with exception of the area around the plug stem.Pressure-balanced plugs are additionally sealed with a PTFEring or a graphite ring. The pressure-balanced components aresubject to wear. As a result, the seat leakage rate (see Table 2)and the amount of maintenance needed for these valvesincrease. Pressure-balanced plugs should not be used, if at allpossible, for high-temperature process media or for media thatcontain solids or crystallize out. In these cases, we recommendto use a more powerful actuator.

Control valves with ceramic trims (T 8071 EN)Control valves with extremely resistant ceramic trims are usedwhen the valve body and the trim are subject to considerableerosion and abrasion.The following valves can be fitted with ceramic trims:

Type 3251 Globe Valve,Type 3256 Angle Valve.

The Type 3256 Angle Valve can be fitted with a ceramicwear-resistant pipe. When the process medium flows in theflow-to-close (FTC) direction, this version is suitable for extremeerosive and abrasive conditions caused by process mediumcontaining solids.Details on ceramic materials and their properties are availableon request.

Low-noise operationFlow dividers (T 8081 EN)The flow dividers St I and St III serve to reduce the noise emissionof gases and vapors. The process medium reaches its maximumvelocity after passing the restriction between seat and plug. Be-fore it starts to create a noise-intensive, turbulent mixing zone,the process medium hits the inner wall of the flow divider. Theflow is divided and a low-noise impulse exchange with the sur-rounding medium takes place.

The valve-specific correction values for gases and vapors arerequired for noise calculation according to VDMA 24422, Edi-tion 1989 and DIN EN 60534 when flow dividers are used. Re-fer to the diagrams on page 30 for details.For further details regarding noise calculation, refer to the DINEN 60534 standard or contact us and we will perform thesecalculations for you.The KVS coefficient of the valve trim is reduced on using a flowdivider.The associated data sheets include the KVS I for the flow dividerSt I and KVS III for the flow divider St III.

AC trims (T 8082/3 EN)AC-1 and AC-2 Trims are optimized trims for low-noisepressure letdown of liquids at differential pressures up to40 bar. The seat is raised and the parabolic plug is additionallyguided in the seat.The AC-2 Trim additionally has up to four attenuation plates.

The three-staged AC-3 Trim is used for differential pressures upto 100 bar. Optionally, stellited hard facings or hardened trimsare available.

SilencerThe silencer acts as a fixed restriction that can be installeddownstream of the valve with one to five attenuation plates forapplications with gases or vapors. The silencer increases thebackpressure downstream of the valve which leads to a reduc-tion in the valve outlet velocity and sound pressure level.

Additional componentsBellows sealIn case, stricter emissions control requirements must be met, e.g.TA-Luft or in vacuum applications, a metal bellows is used toseal the plug stem. The plug stem is additionally sealed with apacking at the top flange. This packing serves as a backuppacking.The metal bellows can be monitored for leakage or a sealingmedium can be applied by means of a test connection.The bellows seal can be used for valves ofSeries 240 from –200 to +400 °C, andSeries 250/280 from –200 to +450 °C.

Insulating sectionThe application range of a standard packing can be extendedto an operating temperature of less than –10 °C or over+220 °C by using an insulating section.

The temperature ranges of the various valves series are:Series 240

–200 ... +450 °C Long insulating section–50 ... +450 °C Short insulating section

Series 250–200 ... +500 °C

Heating jacketSome process media only flow easily above a certain tempera-ture. Below this temperature they start to solidify or crystallizeout. The valve bodies are fitted with a heating jacket to ensurethat the process medium remains at a certain temperature andcan flow freely. The valve bonnet may also be equipped with aheating jacket when the plug stem is sealed by a bellows seal.

A heat transfer medium flowing between valve body and heat-ing jacket ensures that the process medium is kept at a certaintemperature. If steam is used as heating transfer medium,proper condensate discharge must be ensured. Versions withconnecting flange heating or enlargened connecting flanges forthe body are available on request.

For control valves according to DIN standards, the weldingends conform to EN 12627.For control valves according to US standards, the welding endsare specified in ASME/ANSI B16.25.For installation methods according to US standards, valves ofthe Series 240 are available with NPT female thread in sizes ½”to 2”.

Valve-specific parametersKVS coefficientThe necessary KV coefficient is calculated according toDIN EN 60534 from the specified operating data.The KVS coefficient is specified in the data sheets to identify thevalves. It corresponds to the KV coefficient at the rated travelH100. In order to increase control accuracy and with regard tomanufacturing tolerances, the selected KVS coefficient must behigher than the KV coefficient.

RangeabilityThe rangeability is the quotient of KVS/KVR. KVR being thesmallest KV where the characteristic still lies within thepermissible gradient tolerance of the characteristic(DIN EN 60534 Part 2-4).

Inherent characteristicThe characteristic shows the relationship between the KV flowcoefficient and the travel (H).Control valves are either designed with an equal percentage(2) or with a linear (1) characteristic.The equal percentage characteristic can be identified by equalincrements of travel that yield equal percentage increments ofthe KV flow coefficient.Whereas, in a linear characteristic, equal increments of travelyield equal increments of the KV flow coefficient.

Valve characteristic: 1- linear, 2 - equal percentage


ActuatorsActuators convert the control signal issued, for example, by apositioner into a travel motion carried out by the control valve(plug stem with valve plug).We supply pneumatic, electric and electrohydraulic actuatorsas well as hand-operated actuators (see Information SheetT 8300 EN).

Pneumatic actuatorsThese are used for pneumatic or electropneumatic controlequipment. Pneumatic actuators are diaphragm actuators witha rolling diaphragm and internally fitted springs. The benefits ofpneumatic actuators include their low overall height, strong po-sitioning force and fast response.Different signal pressure ranges are available. Pneumatic actu-ators are suitable for use in hazardous areas as well as featur-ing a fail-safe action: Upon air supply failure, the control valveis either closed or opened.The Type 3277 Pneumatic Actuators allow direct attachment ofpositioners or limit switches. This prevent the travel linkage frombeing misaligned as it is located within the yoke below the actu-ator housing.Pneumatic actuators can additionally be equipped with ahandwheel (see T 8310-1 EN and T 8310-2 EN).

Electric actuatorsIf compressed air is not available, electric actuators with strongpositioning forces and large travels may be used. These actua-tors are self-locking.Electric actuators are connected to three-point stepping control-lers, electric positioners issuing analog signals or over a revers-ing contactor unit (see T 8330 EN).

Electrohydraulic actuatorsThese actuators are connected to an analog signal viathree-point stepping controllers or electric positioners. Versionswith fail-safe action are available (see T 8340 EN).

Hand-operated actuatorsThey are attached to Series 240 and 250 Control Valves whichare used as hand-operated control valves with rated travels of15 or 30 mm (see T 8312 EN). Hand-operated actuators withlarger travels are available on request (Type 3273-5/6).

Accessories for control valvesSAMSON control valves can be equipped with several addi-tional accessories. These accessories are, for example, used foractuator control and travel indication. They are attached eitheraccording to IEC 60534-6 (NAMUR rib) or directly in conjunc-tion with the Type 3277 Pneumatic Actuator (see T 8310-1 EN).For direct attachment, the entire travel linkage is located in aclosed housing in order to prevent contamination, misalignmentas well as personal injury (see Information Sheet T 8350 EN fordetails).

PositionersPositioners (p/p or i/p) compare the signal of pneumatic orelectric control equipment to the travel (manipulated variable)of the control valve. They issue a pneumatic signal pressure asthe output variable. The positioners can be used in standard op-eration or in split-range operation (see T 8351 EN ff.).Positioners from the Series 3730 include an integrated firm-ware for valve diagnostics which issue alerts for predictivemaintenance action (EXPERT and EXPERT+, see T 8388 EN).Smart versions (HART, PROFIBUS-PA, FOUNDATION™Fieldbus) are configured and operated using a PC or handheldterminal (see T 8380/-82/-83/-84 EN).SAMSON’s own TROVIS-VIEW software serves as a standardoperator interface to operate these smart positioners (seeT 6661 EN).

Limit switchesWhenever an adjustable limit value is exceeded or not reached,a signal is issued. Inductive limit switches are frequently used.However, versions with electric or pneumatic microswitches arealso available (see Information Sheet T 8350 EN).

Position transmitter/potentiometerTo indicate the travel position of a control valve, the rated travelrange is represented by an analog electric signal (seeT 8363 EN).

Solenoid valvesThe binary signals from control equipment are converted intobinary pneumatic control signals. As a result, the control valvecan quickly be brought into its final position. The solenoidvalves are used for on-off valves or for control valves withfail-safe position (e.g. Type 3241 typetested, T 8016 EN; T3701 EN).

Lock-up valveIf the supply air pressure falls below an adjusted value, the sig-nal pressure line is shut off. When this happens, the actuatorstops in its last position (see T 8391 EN).

Pneumatic remote adjusterManually adjustable precision regulator for the set point adjust-ment of pneumatic control equipment.

Supply pressure regulatorsSupply pressure regulators provide pneumatic control valveswith a constant air pressure (adjustable between 0 and 6 bar)(see T 8546 EN).

Supply pressure regulator with air filterThey consist of a supply pressure regulator and an air filterholding back foreign particles, oil and/or condensate (seeT 8546 EN).

Pneumatic volume boosterThe actuating time can be made shorter for fast control loops byusing pneumatic volume boosters.

Valve sizingCalculating the KV coefficientThe KV coefficient is calculated according to DIN EN 60534.The data sheets contain the necessary device-specificspecifications.A preliminary, simplified calculation may be made with the helpof the working equations listed below. They do not take into ac-count the influence of the connecting fittings or choked flow atcritical flow velocities.

Selecting the valveAfter calculating the KV coefficient, the corresponding KVScoefficient of the valve type in question is selected from the datasheet.In case, real operating data are used in the calculation, thefollowing generally applies: Kvmax ≈ 0.7 to 0.8 · KVS.

Gases and vaporsThe noise emission of single-stage and multi-stage controlvalves for gases is determined according to DIN EN 60534,Part 8-3. This calculation method, however, does not apply tocontrol valves with noise-reducing equipment such as flow di-viders St I and St III. In this case, the calculation must be carriedout according to VDMA 24422, Edition 89.The calculation is based upon the jet power reached on expan-sion. The noise emission is determined by means of an acousti-cal conversion coefficient η G. Diagram 1 illustrates the differ-ence between the conversion coefficients depending on the dif-ferential pressure ratio. This clearly shows the level difference ofthe internal sound powers and the sound pressure levels to beexpected at one meter distance from the pipeline.For a differential pressure ratio of, for example, x = 0.5, the dif-ference in sound pressure levels between a valve with and with-out flow divider is –20 dB.

LiquidsThe noise emission on throttling liquids is calculated accordingto DIN EN 60534, Part 8-4. This calculation is consistent withthe calculation according to VDMA 24422, Edition 89. It isbased on the jet power reached in the valve and also on thevalve-specific acoustical conversion coefficient η F empiricallydetermined according to VDMA 24423 for turbulent flows aswell as the valve-specific pressure ratio xFz at the beginning ofcavitation.The sound power level and the sound level difference at a dis-tance of 1 m for the valves with different xFz values can be seenin the diagram 2.For a pressure ratio of xF = 0.5, and a valve with xFz = 0.6, thesound level which is 20 dB less than that of a valve withxFz = 0.3.

Principle of operation (Figs. 2 to 4)The process medium flows through the valve in the direction in-dicated by the arrow. The valve plug position determines thefree area between the valve seat and the plug. The additionalstem guide is located in the bottom body flange.A pressure-balanced plug (Fig. 3) can be used when high pres-sures or differential pressures act on the valve plug and the forceproduced by the actuator is insufficient.Fig. 4 shows the control valve version with a bellows seal. A testconnection allows the stainless steel bellows to be monitored.The control valves can be fitted with Flow Dividers St I (Fig. 4) orSt III for a further reduction in the noise level (see Data SheetT 8081 EN for details).

Fail-safe positionDepending on how the compression springs are arranged in theactuator (see Data Sheet T 8310-1 EN or T 8310-2 EN for de-tails), the control valve has two different fail-safe positionswhich become effective upon supply air failure:Actuator stem extends (FA)The actuator springs close the valve when the supply air fails.Actuator stem retracts (FE)The actuator springs open the valve when the supply air fails.

Notes on differential pressure tablesThe differential pressure tables were prepared under the follow-ing conditions:– Direction of flow: FTO– Valve plug version with metal sealing or soft sealing– Version with PTFE packing– Tables 4a and 4b for unbalanced plug with downstream

pressure p2 = 0 bar– The leakage rate stated in Table 1 is not exceeded with the

maximum differential pressures listed and the previouslymentioned conditions

– All pressures mentioned are in bar (gauge)– The differential pressure stated can be limited by the pres-

sure-temperature diagram

Note on fail-safe position "Valve CLOSED": For actuators withreduced travels, pretensioned spring ranges must be used.

Note: Permissible differential pressures for special versions withsoft sealing or lapped-in metal plugs, with metal bellows seal orbalanced plug with graphite ring are available on request.

Principle of operation (Figs. 2 to 4)The process medium flows through the valve in the direction in-dicated by the arrow. The valve plug position determines thefree area between the valve seat and the plug. The additionalstem guide is located in the bottom body flange.A pressure-balanced plug (Fig. 3) can be used when high pres-sures or differential pressures act on the valve plug and the forceproduced by the actuator is insufficient.Fig. 4 shows the control valve version with a bellows seal. A testconnection allows the stainless steel bellows to be monitored.The control valves can be fitted with Flow Dividers St I (Fig. 4) orSt III for a further reduction in the noise level (see Data SheetT 8081 EN for details).

Fail-safe positionDepending on how the compression springs are arranged in theactuator (see Data Sheet T 8310-1 EN or T 8310-2 EN for de-tails), the control valve has two different fail-safe positionswhich become effective upon supply air failure:Actuator stem extends (FA)The actuator springs close the valve when the supply air fails.Actuator stem retracts (FE)The actuator springs open the valve when the supply air fails.

Fig. 1 · Type 3252-7 High Pressure Valvewith Type 3767 Electropneumatic Positioner

116 Data Sheet T 8053 EN 2007-10

Principle of operationThe process medium flows through the valve in the direction in-dicated by the arrow. The position of the plug determines thecross-sectional area of flow between the seat and the plug. Theplug stem is connected to the actuator stem by a stem connectorand sealed with a self-adjusting packing. In case stricter emis-sions requirements are specified, the valve can be equippedwith a multiple-walled metal bellows.

Fail-safe positionDepending on how the compression springs are arranged in theactuator (see Data Sheet T 8310-1 EN for details), the controlvalve has two different fail-safe positions in case the supply airfails:Actuator stem extends (FA)Whenever the supply air fails, the valve closes.Actuator stem retracts (FE)Whenever the supply air fails, the valve opens.

The position of the valveplug (3) determines the cross-sectional area of flow between theseat (2) and the plug.The plug stem (6) is connected to the actuator stem (8.1) via thestem connector (7) and sealed with an adjustable packing (4).To comply with stricter environmental emissions requirements,the valve can be equipped with a double-walled metal bellows(10).The anti-rotation device (13) prevents loosening of the screwconnection between the valve body (1) and the bonnet (5) or theintermediate piece (9).

Fail-safe positionDepending on how the springs are arranged in the actuator (8)(see Data Sheet T 8310-1 EN for details), the control valve hastwo different fail-safe positions:Actuator stem extends (FA)The valve is closed upon air supply failure.Actuator stem retracts (FE)The valve is opened upon air supply failure.

Principle of operationThe process medium flows through the valve in the direction in-dicated by the arrow. The cross-sectional area of flow acrossthe perforated cage is determined by the edge of the valve plug.The arrangement and size of the bores in the perforated cagedetermine the valve characteristic and the flow coefficient. Withtwo-stage plugs, the pressure is further reduced by a down-stream perforated plug.In valves with three-stage plugs (only for liquids), an additionalstage is located downstream of the seat ring. The seat ring iskept inside the body by the cage and can be removed withoutspecial tools.

Fail-safe actionDepending on how the compression springs are arranged in theactuator (for details refer to Data Sheets T 8310-1 EN andT 8310-2 EN), the control valve provides two fail-safe actionsthat become effective when the supply air fails.

Actuator stem extends (FA):The valve is closed when the supply air fails.Actuator stem retracts (FE):The valve is opened when the supply air fails.

Principle of operationThe medium flows in the flow-to-open direction through thevalve. The valve plug determines the cross-sectional area offlow. The KV coefficient is adapted over the plug and, if neces-sary, using a combination of attenuation plates upstream of theseat.To avoid vibrations, the plug is double guided by a guide bush-ing at the top and a second guide in the seat.

AC-1Compared to standard valve trims, these trims considerably re-duce the sound pressure level for differential pressure ratios be-tween XF = 0.25 and XF = 0.75 by shifting the point of incipientcavitation.Depending on the valve load, the sound pressure level is re-duced to varying degrees.

AC-2Optionally one to four attenuation plates can be integrated inthe seat on the upstream side. In this way, the point of incipientcavitation is shifted at large valve loads to higher differentialpressure ratios XF.For small valve loads, the onset of cavitation is shifted by higherXfz values of the parabolic plug to higher differential pressureratios.Compared to standard valve trims, these trims considerably re-duce the sound pressure level for differential pressure ratios be-tween XF = 0.25 and XF = 0.9 by shifting the point of incipientcavitation.

The differential pressure ratio XF is defined as

XF =Δp

p pv1 −

with Δp being the differential pressure across the valve, p1 be-ing the upstream pressure, and pv representing the vapor pres-sure of the medium.The reduction of the sound pressure level ΔLpa compared to astandard valve trim is exemplified in Figs. 5 and 6. The dia-grams illustrate four different valve loads.

Principle of operationThe medium flows through the valve in the flow-to-open direc-tion. The valve plug determines the cross-sectional area of flow.To avoid vibrations, the plug is double guided by a guide bush-ing at the top and a second guide in the seat.Compared to standard valve trims, the AC-3 Trims considerablyreduce the sound pressure level for differential pressure ratiosbetween XF = 0.25 and XF = 0.95 by shifting the point of incipi-ent cavitation.Depending on the valve load, the sound pressure level is re-duced to varying degrees.

The differential pressure ratio XF is defined as

XF =Δp

p pv1 −

with Δp being the differential pressure across the valve, p1 be-ing the upstream pressure, and pv representing the vapor pres-sure of the medium.

The reduction of the sound pressure level ΔLpAa compared to astandard valve trim is exemplified in Fig. 3. The diagramillustrates four different valve loads.

valve and the pipe flange. The nominal size of the silencercan either be the same as the nominal valve size (Type3381-1.1, Fig. 3) or the same as the following expander(Type 3381-1.2, Fig. 4).Depending on the KV/CV coefficient of the attenuation plateseither Type 3381-1.1 or Type 3381-1.2 is used.

– Type 3381-2 · A combination of the Type 3381-1.1 andType 3381-1.2, always with two attenuation plates.This version can only be used with certain KV/CV coefficientcombinations as the attenuation plates are mounted directlybetween the valve and pipe flange, not requiring a separatehousing.The pipe expander is not scope of the delivery of bothversions (Type 3381-1.x and Type 3381-2).

– Type 3381-3-x · Silencer with two to five attenuation plateslocated in one housing. The “x” in the type designation indi-cates the number of attenuation plates. A pipe expander sim-ilar to the Types 3381-1.x and 3381-2 is not required since itis already provided by the housing holding the attenuationplates. The scope of delivery includes all parts necessary forinstallation including bolts.

Principle of operationThe Type 3381 Silencer provides noise attenuation by acting asa fixed restriction. The silencer raises the pressure of the me-dium flow at the valve outlet and reduces the pressure down-stream of the silencer to the required downstream pressure p2.As a result, the sound pressure level is reduced. In applicationsusing compressible media, it additionally lowers the flow veloc-ity at the valve outlet.The pressure reduction per attenuation plate (Δp) depends onthe flow rate and the prevailing operating temperature. Gen-erally, the pressure reduction is between 5 and 7 bar.A five-stage silencer (Type 3381-3-5) normally provides a max-imum pressure drop of 35 bar.

Selecting and sizing the silencer and the upstream controlvalveThe silencer should always be sized together with the upstreamcontrol valve to achieve the best results.1. Calculate appropriate KV coefficient according to

IEC 60534.2. Select nominal valve size from Table 2.3. Select materials, pressure and temperature from Table 1

and from the associated pressure-temperature diagram(see T 8000-2 EN).

The number of attenuation plates and the nominal size is deter-mined from the operating data at hand.

DimensionsThe dimensions of Type 3381-3-x depend on the number ofattenuation plates and the pressure rating. More details areavailable on request.

The following details are required on ordering:Operating pressure in bar (a), bar (g), psi (a), psi (g)

Principle of operationWhen the perforated plug leaves its seat, the steam inlet boresof the first controlled stage are opened, and steam is admittedinto the central chamber. From there, it passes into the atomiz-ing steam cooler through bores at the bottom of the chamber.As the perforated cylinder has only moved a short distance(<20 % of the total travel), the bores for the second stage pres-sure drop are not yet released. This ensures that adequatesteam always flows to the atomizing steam cooler, eliminatingthe risk of water droplets inadvertently being injected into thesystem.As the perforated plug continues to lift, more steam inlet boresare released in a pattern corresponding to the desired openingcharacteristic.Once the perforated plug has lifted more than 20 %, the boresfor the second controlled stage are opened, allowing steam toflow from the central chamber through the second stage bores,and into the throttling cylinder. This pressure reduced steamflows through the uncontrolled perforated attenuation plates forfurther pressure reduction, and continues downstream to thetemperature sensor.When the steam comes into contact with the temperature sen-sor, a signal is sent to the spray water control valve, opening thevalve and admitting spray water into the steam cooler. Thisspray water is atomized by the kinetic energy of the steam,which is continuously flowing through the cooler. The atomizedwater is instantly vaporized by the superheated steam. The flowfrom the second controlled stage passes through the perforatedattenuation plates, and comes in contact with the flow from theatomizing steam cooler. Here the two flows mix, ensuring totalevaporation of the spray water. This completes both the pres-sure and temperature reduction.The perforated attenuation plates installed after the second con-trolled stage, provide additional pressure drop, noise reduc-tion, and lower outlet velocity.

General

Water bath desuperheaters are used if processes have to be hea-ted with saturated steam, but where only superheated steam isavailable which must be desuperheated to saturated steam tem-perature. This is not possible with steam converting valves or in-jection desuperheaters, since it is possible to desuperheat onlydown to approx. 5 °C above saturated steam temperature withthese. If the pressure of the available steam is too high or an ad-justable saturated steam pressure is required, the water bath de-superheater can be designed in addition with pressure control.

Processes which are heated with saturated steam frequently re-quire only small quantities of steam, but with delivery fluctuationsbetween 0 and 100 %. Here the water bath desuperheater isideally suitable, since it guarantees perfect desuperheating overthe entire load range.

Applications in which the product has to be heated directly withsaturated steam are for example:● Agers and decatizing vessels in the textile industry● Pasteurizers in the food industry● Sterilizers in the chemical industry● Steam boxes in the paper industry

Applications in which the products have to be heated throughheat exchanger surfaces where overheating of the product mustbe surely avoided are for example:● Heat exchangers for pasteurizers and sterilizers in the food

industry● Heating systems for dry rolls in the paper industry● Heating systems for reaction vessels and pipelines in the che-

mical industry

The Type 994 - 0001 water bath desuperheater has the followingfeatures:● Desuperheating superheated steam to saturated steam tempe-

rature● Pressure reduction of superheated steam● Control range 0 ... 100 %● Operating overpressure max. 11 bar, higher pressure on request● Saturated steam pressure max. 11 bar, higher pressure on request● Saturated steam temperature max. 187 °C● Steam throughput max. 40 t/h, depending on the saturated steam

pressure● Pressure vessel made from H II (mat. no. 1.0425) or CrNiTi

cate, other certificates on request● Version with fastening supports● Version with liquid level control● Version with liquid level control and pressure control● Version with liquid level control, pressure control and process

Construction

The Type 994 - 0001 water bath desuperheater consists of a pres-sure vessel [1], which is protected against thermal losses with aninsulation [2]. The superheated steam flows from above througha pipe [7] into the interior of a flow divider [4], which is com-

pletly surrounded by cooling water. The cooling water is fed infrom below through a pipe [3] into the pressure vessel [1]. Thesteam arising bubbles out from the flow divider [4] at the watersurface and escapes as saturated steam. The saturated steam iscarried out from the pressure vessel [1] through a pipe [8]. Theliquid level of the cooling water is monitored with two limit swit-ches [5] and [6]. An overflow [9] is fitted above the maximumliquid level in order to avoid overfilling of the pressure vessel [1]on failure of the liquid level control system.

Type 994 - 0001 Water Bath Desuperheaterfor desuperheating superheated steam to saturated steam temperature

220 Data Sheet B 016 EN 2007-03

Operation

Water bath desuperheater with liquid level control

The superheated steam is introduced into the cooling water. Inthis case the superheating heat is transferred into the cooling wa-ter which is converted into saturated steam when the boiling tem-perature is reached. The evaporated portion is replaced by coo-ling water with a liquid level control system. On reaching theminimum liquid level, the condensate valve [1.4] is opened via alimit switch [1.3] and closed when the maximum liquid level isreached. On failure of the liquid level control system the coolingwater is diverted through a condensate diverter [1.6].

Pressure regulation

Saturated steam pressure and saturated steam temperature areassociated with one another physically. In the version with pres-sure regulation, the saturated steam pressure is converted into ameasurement signal which is conducted to a pressure controller[2.3] through a pressure transmitter [2.2]. The output signal ofthe pressure controller [2.3] operates the steam pressure controlvalve [2.5] through a positioner [2.4]. Thus the pressure of thesuperheated steam can be reduced and cooled to desuperheatedsteam temperature.

Process temperature control

In the version with process temperature control the measurementsignal of a temperature sensor [3.1] is conducted to a temperatu-re controller [3.2], the output signal of which operates the tempe-rature control valve [3.4] through a positioner [3.3]. In this casethe pressure drop at the temperature control valve [3.4] must bekept low so that the saturated steam temperature is as close aspossible to the load temperature to be controlled.

Safety equipment

The operating pressure in the pressure vessel [1.1] of the waterbath desuperheater is limited to the permissible value by meansof a safety valve [2.6.3]. A safety pressure limiter [2.7.1] and asafety temperature limiter [2.7.2] ensure that the pressure andtemperature at the saturated steam outlet do not exceed the per-missible values. Whenever the pressure and temperature reachthe respective limit values, the steam pressure control valve [2.5]is closed via a solenoid valve [2.7.3].

Installation examples

Heating agers in the textile industry (Fig. 4)

Statement of the problemAn ager for coloured textile webs has to be heated with steam ina temperature range of 100 to 110 °C. The steam may only beslightly overheated in order to avoid stains forming on the textilewebs at the entry places into the ager. In addition, the steammust be dry so that no water stains can occcur.

Solution of the problemSuperheated steam is reduced in pressure and desuperheated tosaturated steam temperature in a water bath desuperheater withliquid level control and electropneumatic pressure regulation. Thecooling water is fed into the pressure vessel from a separate wa-ter network. The temperature of the ager is kept constant even onload changes (e. g. changing running speeds or changing speci-fic weight of the textile webs) with a a process temperature con-trol. The maximum temperature of the ager is limited by the setsaturated steam pressure. In order to avoid overheating of theager in the case of the fault, the temperature control valve is de-signed for a slight pressure drop so that the saturated steam tem-perature is as close as possible to the ager temperature to becontrolled. The components of the water bath desuperheater areinstalled in a frame ready for connection as complete system.

Heating vessels and pipelines in the chemical industry (Fig. 5)

Statement of the problemThe vessel and the pipelines of a SO3- conditioning plant have tobe heated with steam and the heating temperature must be keptwithin tight limits. The condensate arising on heating should beused as cooling medium.

Solution of the problemSuperheated steam is reduced in pressure and desuperheated tosaturated steam temperature in a water bath desuperheater withliquid level control and electropneumatic pressure regulation. Thehot condensate arising on heating the vessel and the pipelines isconduced into a pressureless collecting vessel and cooled downby the ambient air. Excess condensate is delivered to the conden-sate network through an overflow. The flash steam arising on con-densate diversion is diverted over the roof. The cooled condensateis fed into the pressure vessel of the water bath desuperheater ascooling medium using cooling water pressure elevating pumps.Thus the collecting vessel has to be filled with cooling water onlybefore the first time the plant is started up. A safety pressurelimiter is installed at the steam inlet and a safety limiter at thesteam outlet to protect the plant. The cooling water pressureelevating pumps are equipped with dry running protection andautomatic fault switchover. The components of the water bath de-superheater are installed in a frame ready for connection ascomplete system.

Principle of operationThe signal pressure pst generates a force F = pst · A on the dia-phragm area A (2). This force is balanced by the actuatorsprings (4). Taking into account the rated travel, the number ofsprings and their compression determine the bench range. Thetravel H is proportional to the signal pressure pst. The operatingdirection of the actuator stem (7) depends on the arrangementof the springs and the signal pressure connection (1).The stem connector (8) connects the actuator stem (7) with theplug stem (10) of the valve.The adjustable mechanical travel stop (Fig. 12) is suitable foractuators made of sheet steel with effective diaphragm areas of240, 350, or 700 cm². Using the limit stop, the actuator travelcan be limited by up to 50 % in both directions (actuator stem“extends” or “retracts”) and permanently adjusted. A specialversion with one-sided travel stop for actuators with an effectivediaphragm area of 120 cm² is available.

Actuators are available with the following fail-safe actions:“Actuator stem extends (FA)“The springs cause the actuator stem to move to the lower endposition (sectional drawings, right) when the diaphragm is re-lieved of pressure or when the supply air fails.“Actuator stem retracts (FE)“The springs cause the actuator stem to retract (sectional draw-ings, left) when the diaphragm is relieved of pressure or whenthe supply air fails.

Principle of operationThe signal pressure pst generates a force F = pst · A on the dia-phragm area A (2). This force is balanced by the actuatorsprings (4). Taking into account the rated travel, the number ofsprings and their compression determine the bench range. Thetravel H is proportional to the signal pressure pst. The operatingdirection of the actuator stem (7) depends on the arrangementof the springs.The stem connector (8) connects the actuator stem (7) with theplug stem (10) of the valve.Fig. 12 shows the side-mounted Type 3273 Hand-operatedActuator for actuators with effective diaphragm areas of 1400and 2800 cm² and a maximum travel of up to 80 mm. Thehandwheel (23) is fixed to the worm-geared shaft (20) andmoves the actuator stem over the worm-geared wheel (21) andthe threaded bushing (22).A side-mounted handwheel as illustrated in Fig. 14 is availablefor valves with 120 mm travel.The adjustable mechanical travel stop (Fig. 7) is suitable for ac-tuator version 1400-60 as well as 2800 cm² and tandem actua-tors. The actuator travel can be limited by up to 50 % in both di-rections (actuator stem “extends” or “retracts”) and perma-nently adjusted. The tandem actuator (Fig. 6) contains two cou-pled diaphragms; they produce a positioning force that is twiceas high as the force of a single-acting actuator.Actuators are available with the following fail-safe actions:“Actuator stem extends (FA)“The springs cause the actuator stem to move to the lower endposition (sectional drawings, right) when the diaphragm is re-lieved of pressure or when the supply air fails.“Actuator stem retracts (FE)“The springs cause the actuator stem to retract (sectional draw-ings, left) when the diaphragm is relieved of pressure or whenthe supply air fails.Legend1 Signal pressure connection2 Diaphragm3 Vent4 Springs5 Diaphragm cases6 Annular nut7 Actuator stem8 Stem connector9 Coupling nut

TROVIS-VIEWConfiguration and Operator Interface

Software

Data Sheet T 6661 EN 2007-12 253

TROVIS-VIEW is a standard operator interface, allowing theuser to configure and parameterize various SAMSONinstruments using a device-specific database module.Data is transferred between the TROVIS-VIEW software and theSAMSON device either directly (e.g. using a connecting cableor infrared adapter; also see Table 1) or indirectly using amemory pen or memory module.

A direct connection enables both online and offline operation.This means that data can be changed in the device immediately,or they can be saved on the PC first and later downloaded to thedevice on site.

The device-specific modules contain a database providing thecharacteristic properties of each device type, such as parame-ters, data points, user levels, etc. The various user levels canbe protected with passwords.

The available modules are being extended constantly.

Valve flow coefficientsType 3241 Type 3251 Type 3254 Type 3256


Valve characteristicsThis Information Sheet contains valve flow coefficients (accord-ing to IEC 60534-2-3) measured on the SAMSON test benchfor all available nominal sizes and flow coefficients KVS for theType 3241, Type 3251 and Type 3254 Globe Valves as well asfor the Type 3256 Angle Valve.The flow coefficients KV are specified for a travel of up to 110 %to indicate the remaining reserve that the valves have.Note! This overtravel cannot be implemented in valves withbellows seal.

The flow coefficients in Table 4 onwards are specified as CVcoefficients in gallons per minute (gpm) frequently used inAnglo-American regions.You can use the graph paper in pages 300 and 316 to create
