BONETTI ® Piston ValvesGENERAL INFORMATIONSeat tightness in a piston valve is obtained by a cylindrically shapedplug, connected to a spindle, and operated by a hand wheel, whichenables it to move through the inner diameter of two packing rings.When the piston is in the high position, that is, held by only theupper valve ring, (which also ensures tightness to the atmosphere),the valve is open. When the piston is lowered and is held in place byboth the upper and lower valve rings (and thus ensuring seattightness between the valve inlet and outlet), the valve is closed.Because of the use of the packing rings, which have alternate layersof graphite and stainless steel, the piston valve is considered a"soft-seated" valve. The contact between the piston and rings (sealing effect) ispositively assured by means of the pressure exerted by stud boltswith Depending on valve material, belleville washers, are fitted tocompensate expansion due to temperature variations. A typical feature of piston valves - compared with globe valves - isthat the piston is always held by at least one sealing ring. Therefore,there is no vibration during closing and opening operations. Another primary feature of the piston valve is that the two cylindricalseating surfaces, the bottom valve ring and the piston, come incontact when the fluid flow is already nearly cut off. Another uniqueproperty of the BONETTI® Piston Valve is that with the valvecompletely open and the piston completely supported in the innerdiameter of the upper valve ring, i t is protected againsterosive/corrosive elements as well as prevented from having foreignmatter deposited upon it. Piston valves - contrary to globe valves - are bi-directional. That is,they can be installed in a process line in both directions of flow.However, the most common installation is with the fluid inletpressure below the valve piston. Since no metallic sealing surfaces are present, there is perfectinterchangeability of all components. A new set of spares can beimmediately fitted without the need of adaptation to other existingparts. Therefore, inline repairability and maintenance is easy, doesnot require specialized personnel, and will always make the valvelike new.

OPERATING RANGEEngineering companies have been using our piston valvessuccessfully for more than 75 years. Their first application, stillwidely used, was the tight shut-off of low and medium pressuresteam. In later years, piston valves have been selected to meet the severedemands of a large number of requirements in fluid handlingapplications in the industrial sector. As such, they are used inprocess lines containing many different fluids such as steam,superheated water, thermal transfer fluids, ammonia, LPG,hydrocarbons, acids, alkaloids, etc. Their ability to provide perfectseat shut off and packing tightness, and their long term trouble-freeoperation, ensured by our patented reinforced seal rings, haveserved to greatly expand the number and types of applicationswhere the BONETTI® Piston Valves are used. This is particularlytrue of their use in the handling of harmful and flammable fluidswhere tight seat and packing shut off is essential. Although the seat seal rings are suitable for use in temperatures inexcess of 1022°F (550°C), their use is limited to the restrictionsapplicable to the body material, as well as that of other metallicpressure retaining valve components. It should be noted that carbonsteel bodies can not be used in temperatures above 800°F (427°C).

DESIGNPiston valves are usually T-pattern, straight through flow globevalves, with their stem perpendicular to the process line. The present design is the result of our long experience in the designand manufacturing of this product, which began as early as 1926.Our latest designs reflect the remarkable progress in regards to thequality of the sealing rings, particularly for their application in valvessize 2 ½" (DN 65) and larger, as well as for their application inhandling high pressure fluids using balanced pistons and rising,non-rotating spindles. Kindly refer to the details on page 6, wherethe BVe valves are described. (Please note: "e" means balancedpiston.)

OPERATIONSPiston valves are typically shut-off valves. But by replacing thestandard lantern bushing with a characterized regulating lanternbushing, the valves can be turned into control valves to provide acharacterized flow pattern, having manual or automatic service.Since the piston is always held by the upper valve seal ring, novibration can occur.

Piston type flow control valves, contrary to globe type flow controlvalves, offer perfect seal tight shut off. Thus, a very interestingapplication of piston valves is their use as regulating or modulatingvalves in severe service applications. (See details on page 16.)

RATINGSFor reference purposes, the maximum operating pressure of apiston valve is directly related to the operating temperatures asshown on table Figure 1061, on page 2. The actual maximumoperating conditions are those stated in the ASME B16.34 tables forthe given material and pressure class. In cases where severe duty will be experienced, such as thermalshock vibrations, repeated stresses, condensate hammering, andthe handling of harmful or dangerous fluids, the customer shouldconsult with the factory for the proper selection of materials ofconstruction. When soliciting a quotation or sending an inquiry, it isnecessary that you supply the worst operating conditions, includingtype of fluid, inlet and outlet pressures, and temperatures.

MATERIAL SCHEDULESThe term "Material Schedule" refers to the types of materials of thevarious components of the valve. Kindly refer to Figure 1062 -Material Schedules, below. All valves may contain some copper bearing alloys, externally andnot in direct contact with the fluid. In cases where this is notdesirable, the factory can substitute these materials for specialalloys. In such cases, a special material schedule designation, "H",shall be used. (ie.: "G/H", "FS/H", "F/H", etc.).

BONETTI Piston Valves

Fig. 1004 Fig. 1046Type BK

Figure 1004 shows the basic design of a BONETTI® Piston Valve.The valve consists of a body (1), which is internally fitted with twosealing rings. The lower valve ring (2.1) ensuresupstream/downstream seat tightness. The lantern bushing (3) is thespacer between the valve rings. The upper valve ring (2.2) ensurestightness to the atmosphere. The two valve rings are compressedby the bonnet (9), which is compressed by the stud bolts and nuts(10) and by the Belleville washers (11). The latter compensates forexpansion due to temperature variations.

The piston (4) is connected to the spindle (6), which is actuated bythe hand wheel (7). When the piston is in the high position and fullyencircled by the upper valve ring, the valve is open. When thepiston is lowered into the inner diameter of the lower valve ring, thevalve is closed. The opening stroke ends when the split nut (5)contacts the bonnet (9). The closing stroke ends when the handwheel (7) contacts the bonnet (9). The following BONETTI® Piston Valves are manufactured inaccordance to figure 1004. - Size 3/8" (DN 10) through size 2" (DN 50) for API 602 - ASME

Class 800 and for DIN PN 16 - PN 40; - Size 2 ½" (DN 65) through size 6" (DN 150) for ASME Class 150

and for DIN PN 16.The valves, using this design, are fitted with non-balanced pistonand are denominated BVn, where the "n" means "non-balanced." Allvalves are further fitted with anti-friction threaded bushings in thebonnet and a thrust plate between spindle and piston.

Figure 1046 shows a BONETTI® Piston Valve, type BK, which isessentially the same design as figure 1004 but which is suitable forhigh pressure service in sizes 2 ½" (DN 65) to size 6" (DN 150). The coupling between the threaded spindle (6) and the piston (5) isobtained by means of a split ring (12) and a piston nut (11). Actual force for valve closing is exerted by a thrust plate (13). Theoverall dimensions of figure 1046 valves are identical to those ofother valves having the same size and pressure class with regardsto body length and flanges. However, there are some deviations inthese dimensions, and they are:

BONETTI® piston valves are particularly well suited for use inrailway and truck tankers used for the transportation of liquids suchas LPG, ammonia, and other hydrocarbons. Currently, manytankers are equipped with BONETTI® piston valves type BK. Thesevalves have been approved by the German authority TUV.

Type BVe

Fig. 1020.1

Figure 1020 shows a BONETTI® Piston Valve type BVe with balanced piston (the "e" means balanced) and with rising, non-rotat-ing stem. This design is required when the inlet pressure against thepiston reaches such high values that the operation of the valvebecomes difficult. By releasing some of the inlet fluid pressurethrough a hole in the balanced piston and against the bonnet (37)the piston is then in balance and the valve becomes easier to oper-ate. The valve is equipped with a standard gland nut (13) and packingrings (12.1 and 12.2). The following are also integral components ofthis new design of piston valves: - Threaded stem (36) is rising and non-rotating. - Integral anti-rotating device (23), which is also used as a stroke

indicator. - Perfect tightness when back seating is obtained by the back

seat (32) wedging itself between the stem (36) and the bonnet (37)in an actual non-rotating motion

- Operating torque reduced by two roller bearings (30)

Valve Body SealValve body seal tightness between body (1) and bonnet (37) is alsoensured by an additional auto-sealing ring (35), which provides atight seal. A perfect, durable body/bonnet seal is thus achieved. Byso doing, we eliminate the need to use a third ring, which would takeup considerable space and prevent the stud bolts from exerting therequired pressure to the lower valve seat ring (2.1). All BONETTI® Piston Valves are equipped with specialgraphite/metal alloy rings with the following features and advan-tages: - Elimination of asbestos rings (environmentally sound practice). - Wear and erosion resistance to nearly all types of fluid. - Remarkable temperature stability and, consequently, substantial

increase in the operating range, making it suitable for very hightemperatures, since the limits of operation become a function ofthe body material and not of the seating rings.

- Reduced coefficient of friction resulting in longer life of both upperand lower sealing rings, as well as longer life for other componentssuch as the threaded stem bushing, etc.

For special applications, PTFE valve rings can also be supplied onrequest. The following BONETTI® piston valves are manufactured in accor-dance to figure 1020 BVe: - from size 2. ½" (DN 65) to size 8" (DN 200) for:- ASME Class 150 - 300 and DIN PN 16 - PN 40

Flow Coefficient

BONETTI® Piston Valve Flow Coefficient

Based on theory and experimentation, a series of mathematicalequations have been developed which facilitate the estimation of avalve’s ability to handle a fluid based on the type of fluid, the inletpressure, and the temperature.

The use of the aforementioned equations can yield a parameter,which is often constant within certain limits, and directly related tothe type of valve and its internal dimensions and configuration. Theparameter can then be proven through testing and experimentationand, thus, becomes valid for an entire series of similar valves, forall operating conditions. Once established, this parameter can bean effective aid in the selection of a valve size suitable for properhandling of a set of flow conditions.

This parameter, which is known as Flow Coefficient, is used toestimate the volume of water, under standard conditions, that canflow through a valve under a stated pressure drop. Accordingly,Flow Coefficient ( stated as Cv under the ASME system, and Kvunder the European system) is defined as:

One Cv is the ability to flow one U.S. gallon of water per minute, at60 °F, through a fully opened valve, under 1 psi pressuredifferential.

One Kv is the ability to flow one cubic meter of water per hour, at20 °C, through a fully opened valve, under 1 bar pressuredifferential.

The Flow Coefficients for the selection of Bonetti Piston Valves areas follows:

Flow Coefficient for Stop Valves

Flow Coefficient for Flow Control Valves

For BVR type Valves, select the Cv and Kv values of a valve havingnominal bore (DN) one size smaller.

For BVR type Valves, select the Cv and Kv values of a valve havingnominal bore (DN) one size smaller.

Although piston valves are primarily used as on/off valves, they arealso suitable for use as modulating control valves. (Please refer topage 4) The flow path for BONETTI® piston valves provides anexcellent means of flow control even when just the standard lanternbushing component is used, and which is not necessarily designedfor modulating flow control. The modulating flow control piston valve design is fitted with alantern bushing (fig. 1070) that has a multiple hole design andwhich will yield and equal percentage flow characteristic. Uponrequest, linear or quick opening flow characteristics are alsoavailable.

We also wish to point out that: The flow control piston valve design provides tight sealing whenclosed, like all other BONETTI® piston valves, and therefore it isnot necessary to use additional valves for shut-off. Even with high differential pressure, our piston flow control valvesdo not allow vibration or noise thanks to their having a continuallyguided piston, which is very much in contrast with that of controlvalves with top guided contoured plugs.

Our piston modulating valves are equipped with actuators operatedby means of signals coming from process controllers.

In order to submit a proper quotation, it is suggested that thespecially designed product data sheet should be submitted to us forevaluation. In most cases, the following data should be sufficient: - Kind of fluid - Upstream and downstream pressure - Operating temperature - Flow rate - Type of controlling signal.

In 1905, Cesare Bonetti opened a shop in Milan, Italy, tomanufacture small hand valves to meet the local demand. Inthe early 1920s, this small but growing firm, took on a newindustrial look and moved into the production and sale ofindustrial valves.

BONETTI®, by this time, had become a well known companyfor the production of piston valves, sleeve-packed cocks,and glass level gauges. Subsequently, the production range,bearing the BONT® and CMI Pasquini® registeredtrademarks was increased to include new valves for hightemperature and high pressure service designed to meet thestrictest requirements of the time and using the mostadvanced design and manufacturing technology. Thisincluded double sealing valves, bellows valves, diaphragmvalves, and magnetic level gauges.

After two expansions, in 1969, the company moved to itsnew headquarters in Garbagnate Milanese, where Bonetti

continues its passion for growth through research,development and design accuracy. This, in turn, increases its opportunities to continue to growand expand.
