Actuators and Accessories

Torque is a rotary force. For gate and globe valve applicationswhich have acme threaded rising stems driven by a drive nut, torqueis conversion of thrust from a purely linear force, utilizing themechanical advantage of a screw to achieve linear movement. Thestem factor used to convert thrust to torque is a function of the acmethread characteristics of the valve stem and drive nut (yokesleeve).Pages AA-3 thru AA-7 contain stem factors for Pacific gate, globeand stop-check valves. Once seating or unseating thrust has beencalculated, the torque can be obtained by the formula:

Torque = Thrust x Stem factor*Example: 6" 150 Ib. Gate valve

Thrust = 2072.2Stem factor = .0099Torque = 2072.2 x .0099 = 20.5 ft. Ibs.

Valve running torque can be calculated utilizing the above formulasubstituting running thrust for seating thrust.

Rimpull is the force which must be applied to the rim of thehandwheel during operation of the valve. Rimpull is calculated usingtorque. The following information is required to calculate handwheelrimpull:

A. Torque required to seat or unseat valveB. Handwheel diameter

Rimpull = Torque ÷ Radius of the handwheelmeasured in feet

Where: The radius of the handwheel =Handwheel Dia. in inches

2The radius is converted to feet = Radius

12

*Example: 6"150 Ib. GateSeating or unseating torque = 20.5 ft. Ibs.Handwheel diameter = 14"

Rimpull = 20.5 ÷ .583 = 35.2 lbs.Where: 14 = 7 = (Radius in inches)

2 712 = .583 (Radius in feet) = 35.2 Ibs.

1. Seating Force = Valve seat area x Max differentialPressure x Valve factor

Where: Valve seat area = (Seat dia)2 x 3.144

Max. differential Pressure = P1- P2

Valve factor = .25 Parallel seat.3 Gate valve

1.1 Globe valve2. Stem Load = Valve stem area x Max. upstream pressure

Where: Valve stem area = (Stem Dia)2 x 3.14 4

Max upstream Pressure = P1

Note that stem load is applicable to gate valves only as this force isincluded in the seating force of globe and stop-check valves.

3. Stem Packing Friction = Stem diameter x 2000 for graphite.

* Example - 6" 150 Ib. gate valve, seat diameter 6", stem diameter 11⁄8",maximum differential pressure 100 PSIG.

1 - Seating force = 28.26 x 100 x .3 = 847.8 lbs.

Where: Seat area = (6)2 x 3.14 4

2 - Stem load = .994 x 100 = 99.4 lbs.Where Stem area = (1.125)2 x 3.14

43 - Stem packing friction = 1.125 x 1000 = 1125

Thrust to seat or unseat = 847.8 + 99.4 + 1125 = 2072.2 Ibs.

The three major forces involved in valve actuation are thrust, torqueand rimpull. Below is a brief description and formula used todetermine each of the three forces for a particular valve application.See pages 3 through 7 for reference data to be used with Pacificgate, globe and stop-check valves to determine thrust, torque andrimpull for a particular application. These pages also show torquefor differential pressures at full and half maximum cold workingpressure for carbon steel valves.

Thrust is the purely linear push-pull force involved in seating andunseating a valve. It is determined using the following valve andapplication criteria:A – The valve seat diameter.

If the valve seat diameter is not known, theport diameter can be assumed to be the seatdiameter for estimating purposes.

B – The maximum differential pressure across the valve seat.The most common method of determiningmaximum differential pressure across the valveseats is to assign the maximum design oroperating pressure the upstream value P1 andassume a downstream pressure P2 of 0 PSIG.

C –The valve stem diameter.

Determining Thrust, Torque and Rimpull

Running rimpull can be calculated by substituting running forseating/unseating torque.

These criteria are used in the thrust calculation which is the sum ofthe following forces. Unit of measure is Ibs. of thrust.

Valve running thrust which represents 90% of the travel of the valve stemcan be determined by adding stem load and stem packing friction.

Possible handwheel orientations are shown in the figure to the rightbelow. Spur gear (SGA) or compound bevel gear (BGA) attach-ments can be provided in any position shown in Figure 1. Typicalconfigurations are shown in Figure 2.

Handwheel OrientationMany applications require gate, globe and stop-check valves touse gearing to reduce the hand wheel rimpull and thus allow oneman to manually seat or unseat the valve. See page 2 for definitionand calculation of rimpull. Standard gear actuators are sized toseat or unseat the valve with a rimpull requirement of less than 250Ibs. Unless otherwise specified the maximum differentialpressure is assumed to equal the valve pressure class, e.g.900 psi for a 900 lb. class valve. If service parameters differfrom above, please consult factory when ordering.When the actual maximum differential pressure is known, or amaximum rimpull is specified which is less than 250Ibs, thisinformation should be provided in your Request for Quotation.

a) Maximum differential shut off pressureb) Maximum allowable handwheel rimpull to seat or

unseat valve

Our standard bevel gear actuator typically includes the followingfeatures*:

1) 2" square air wrench nut.2) Weatherproof, built for outdoor service.3) Motor actuator adaptable.4) Compound gearing available.

* Consult factory when ordering

Figure 1

1. On the average, operators should be capable of lifting theirown weight, using this as a guide maximum rimpull can beestimated, ie; a 175 Ib. man should be able to handle aseating rimpull up to about 175 Ibs. Rimpulls are oftenspecified much lower to avoid operator strain and possibleinjury.

2. Low rimpull requirements often result in the selection ofbevel gears with high gear ratios. This can result in highoperating times due to the number of turns needed to cyclethe valve. Keep this in mind when specifying a maximumrimpull.

3. Air wrench operation speeds up cycle time on high gear ratiobevel gears however, the mechanical advantage availablefrom bevel gearing enables the operator to damage thevalve. Never seat or back seat the valve using an air wrench;manually seat and back seat the valves with caution, espe-cially when equipped with bevel gears.

Remote ActuatorsIn many applications, operation of valvesmay require the use of electric, pneumaticor hydraulic actuators. Such applicationsinclude those where the valve (1) is toolarge or has too high a differential shut-offpressure for manual operation; (2) is notaccessible for manual operation; (3) is partof a system requiring simultaneous opera-tion of many valves; (4) must be triggeredfrom a remote location, as is often essentialfor emergency shut-off in hazardous areas.

We will gladly furnish any type or make ofactuator you specify, or make recommen-dations for your particular service condi-tions. All Pacific gate, globe and non-returnvalves can be supplied with electric, air,gas or hydraulic driven motor actuators orcylinder actuators.

Remote Actuators

1. Valve size, figure number or description.

2. Valve operating conditions (pressure, temperature, flow rate and fluid).

3. Maximum differential (shut-off) pressure.

4. Primary power supply:a) electric-voltage, phase cycles,b) gas or hydraulic-fluid, available flow rate, maximum and minimum

pressure.

5. Control voltage.

6. Valve stem position.

7. Closing time and frequency.

8. Required construction (NEMA, etc.) or local environment.

9. Auxiliary equipment:a) push-button stations,b) reversing controllers,c) position indicators,d) other (i.e., stem covers, etc.)

10. Special requirements (i.e., radiation, seismic, etc.)

11. Preference for specific manufacturer, if any.

Information Required to Quote Motor Actuators

Motor actuators for rising stem valves can be powered by air, gas, hydraulic or electricpower. The most common method of actuation is the electric motor actuator, as it isgenerally the most cost effective.

Electric motor actuated valves can be provided to meet the broadest range of requirementsincluding operating cycle time, use of integral or remote controls, starters and indicators,and a wide range of power sources. They are less readily adaptable to fail-safe operationthan cylinder actuators because they generally require more stored energy.

Air motor actuators are often specified in very hazardous locations where electric poweris not available or permitted. The major disadvantage of this type of actuator is airconsumption, particularly when applied to large valves. The combination of high gear ratioand long stroke can drain an entire air system unless the air supply system is speciallydesigned to accommodate this type of actuator. Like electric motor actuators, these arenot readily adaptable for a fail-safe mode.

Air or gas cylinder actuators include single or double acting, fail openor closed by mechanical spring or pneumatic force. They can bemanufactured to accommodate any length stroke. The limitations ofair cylinder actuators are mechanical spring limits and thrust re-quirements in excess of 75,000 Ibs. Mechanical springs used withair cylinders can be sized for up to 20,000 Ibs. of thrust and have astroke limit of about 14" max. depending on thrust output required.

In applications where mechanical springs can not be used, apneumatic spring provided with stored air pressure is capable ofproviding a fail safe mode. Thrust requirements up to 25,000 Ibs. can

be accommodated with standard bore size cylinders assumingminimum 80 PSIG field air supply. Thrust requirements between25,000 Ibs. and 75,000 Ibs. can be accommodated by boosting orintensifying field air pressure to a higher working pressure for thecylinder and stored locally in a high pressure air tank.

Hydraulic systems are better suited and more economical for thrustrequirements over 75,000 Ibs. Cylinder actuators can be providedwith manual overrides for emergency valve actuation, fail safe modeand other accessories.

Diaphragm actuators available are: double acting (air pressurerequired open or close), direct acting (air pressure required to close,mechanical spring to open) or reverse acting (mechanical spring toclose, air pressure required to open).

This very simple and very economical actuator has applicationlimitations. The first limitation is stroke; a 4" stroke is the longestavailable from most manufacturers. This limits adaptable valve sizeto gate valves 4" and smaller and globe valves in smaller sizes. The

second limitation is output thrust, this is the major constraint inselecting this type of actuator for use with our unbalanced plug globevalves. Most manufacturers can provide diaphragm areas up to 200square inches, however, maximum air pressure allowed for actua-tion decreases. Maximum air pressures are as low as 45 PSIG forlarge area diaphragms available from most major manufacturersthus limiting thrust output. Manual override handwheels are avail-able as an option.

Typical Interlock Lock MountingIncreased security concerns and critical sequencing of pro-cesses have prompted the use of locking devices and interlocksfor valves. While the most basic of locking devices is the chainand padlock, complex process plants are more frequentlyutilizing key interlock systems. Interlock systems are used onvalves when sequencing of valve operation is critical to thesafety of plant personnel, process unit operation or the environ-ment. Interlocks are provided with keys which are released onlyunder specific conditions such as when the valve is fully open.Once the key is released it can be used to open the next valvein sequence. For further detailed information, you may contactthe Interlock Manufacturers.

By-Passes

By-passes serve two purposes. First, they are used in steamservice to warm-up the line before the main valve is opened.Second, they are used on steam and other lines to balance thepressure on both sides of the main valve wedge or disc to aid inopening a large valve.

Pacific valves can be furnished with all welded-on by-passes whenspecified. By-passes are equipped with a single OS&Y globe valvewith a pressure/temperature rating and corrosion resistance equalto or exceeding that of the main valve.

By-PassesGate valve by-passes shall be regularly attached to the side of themain valve with the stems of both valves parallel and pointingupward (between locations A & B).

Globe valve by-passes shall be regularly attached to the right sideof the main valve with the stems of valve parallel and pointingupward. The right side of the globe valve is the side at the right whenfacing the flow port which leads to the underside of the disc(between location E & F).

Bleed, drain and by-pass piping can be furnished with manual orremote actuated valves, as required.Where service conditions warrant larger-than-standard by-passes,it is recommended that the installation of the by-passes be aroundthe main valve.

Main valve size: 11/2"-4" 5"-8" 10"-36"

By-pass size: 1/2" 3/4" 1"

By-passes on valves 4" and larger are furnished to comply withMSS Standard Practice SP-45, Series A.

be used.(c) Material limitations, restrictions, and special requirements are shown on pressure-temperature tables.

NOTES:(1) Repair welding of bolting material is not permitted.(2) Where austenitic bolting materials have been carbide solution treated but not strain hardened, they are designated Class 1 or

Class 1A in ASTM A193. ASTM A194 nuts of corresponding material are recommended.(3) Where austenitic bolting materials have been carbide solution treated and strain hardened, they are designated Class 2 in

ASTM A193.ASTM A194 nuts of corresponding material are recommended.

(4) For limitations of usage and strength levels, see ASME B16.34 para. 5.1.1.(5) Bolts with drilled or undersize heads shall not be used.(6) For ferritic bolting materials intended for service at low temperatures, ASTM A194 Gr. 4 or Gr. 7 nuts are recommended.(7) Acceptable nuts for use with these quenched and tampered steel bolts are ASTM A194 Grade 2 and 2H.(8) Mechanical property requirements for studs shall be the same as those for bolts.(9) These are bolting materials suitable for high temperature service with austenitic stainless steel valve materials.

(10) Only Grades 651 and 660 shall be used.(11) Nuts may be of the same material or may be of compatible grade of ASTM A194.(12) Forging quality not permitted unless the producer last heating or working these parts tests them as required for other permitted

conditions in the same specification and certifies their final tensile, yield, and elongation properties to equal or exceed the requirements for one of the otherpermitted conditions.

(13) Maximum operating temperature is arbitrarily set at 500°F (260°C) unless material has been annealed, solution annealed, or hotfinished, because hard temper adversely affects design stress in the creep-rupture temperature range.

Valve coefficient (Cv) is a number which represents a valve'sability to pass flow. The bigger the Cv, the more flow a valve canpass with a given pressure drop. A Cv of 1 means a valve will pass1 gallon per minute (gpm) of 60° F water with a pressure drop (dp)of 1 PSI across the valve. A Cv of 350 means a valve will pass 350gpm of 60° F water with a dp of 1 PSI.

Technical DataFlow Calculations

The flow coefficient (Cv) listed in the tables apply to fully open valves only.Flow coefficients at other than fully open may be approximated by use of thecharacteristic flow curves for tilting disc check and globe valves. Gate valvesare not recommended for throttling service.

EXAMPLE:What is the Cv of a 12 inch Class 900 Pacific pressure seal globe valve1/4 open?

SOLUTION:From the flow coefficient table above, the fully open Cv for a 12 inch, Class900 globe valve is 1820.

Consulting Figure 2, the percent of fully open Cv at 1/4 valve open is 52%.

The Cv at 1/4 open is then computed as:0.52 x 1820 = 946.

Technical Data

(a) The values in bold face type correspond to the values in the Joint SAE-ASME-ASTM hardness conversions asprinted in ASTM E48, Table 3. (b) Brinell numbers are based on the diameter of impressed indentation. If the balldistorts (flattens) during test, Brinell numbers will vary in accordance with the degree of such distortion whenrelated to hardness determined with a Vickers diamond pyramid, Rockwell brate or other penetrator which doesnot sensibly distort. At high hardness, therefore, the relationship between Brinell and Vickers or Rockwell scalesis affected by the type of ball used. Steel balls (standard or Hultgren) tend to flatten slightly more than carbide balls,

Hardness Comparisons for Steel

resulting in larger indentation and lower Brinell number than shown by a carbide ball. Thus, on a specimen of 640Vickers, a Hultgren ball will leave a 2.55 mm impression (578 Bhn) and the carbide ball a 2.50 mm impression(601 Bhn). Conversely, identical impression diameters for both types of ball will correspond to different Vickersor Rockwell values. Thus, if both impressions are 2.55 mm (578 Bhn) material tested with a Hulgren ball has aVickers hardness of 640, while material tested with a carbide ball has a Vickers hardness of 615 (c). Values inparentheses are beyond normal range.

Technical DataStorage Installation Maintenance

Because valve assemblies are often stored forlong periods before installation, the above con-siderations are also applicable. This means torqu-ing before start-up is required if prolonged stor-age occurs.Distortion of valves, especially lower ANSI pres-sure classes, can occur when piping loads be-come excessive. To prevent this situation, in-spect valve and piping assemblies to insureagainst piping misalignment. External pipe sup-ports should be used to eliminate misalignment.

Bonnet maintenance should, whenever possible,be accomplished without disassembling thevalves. Retorquing bolts is the most effectivemeans of insuring against leaks. However, aspointed out in the chart notes, special conditionsmay require torque modifications. Consult PacificValves when more exacting means are required.NEVER DISASSEMBLE VALVES COVEREDBY FACTORY WARRANTY WITHOUT PREVI-OUSLY CONTACTING PACIFIC VALVES. FAIL-URE TO DO SO MAY VOID WARRANTY. Bon-net gaskets, other than undamaged ring jointtype, should not be reused if valves are disas-sembled.

PACKING—Valve packing should be checkedperiodically to prevent leakage. Tightening ad-justments may be sufficient, but care should betaken not to over compress packing, which maycause excessive valve operating torque. Fromtime to time packing may need to be added orreplaced.

LUBRICATION—Where lube fittings are pro-vided, valves should be lubricated periodically.Stem threads must be bushed with lubricant toavoid damage and excessive torque from devel-oping. Valves should never be operated withunlubricated stem threads or yoke sleeves.

Precautions

Before installing a Pacific valve check the data onthe permanently affixed metal nameplate andany other attached tag against the purchaseorder, to assure that the valve is of the design andmaterial required for the intended service. Makesure that the valve is new and in the factory as-built condition prior to use. All new Pacific valvescarry a limited warranty against defects in work-manship and materials at time of factory ship-ment, but such warranty is voided when valvesare changed in any way. Please see scope oflimited warranty as set forth in the quotation.

While all Pacific valves are tested at the factory toinsure compliance with industry standards andpurchase specifications, they will eventually ex-perience deterioration or wear which could causeleakage or malfunction. A preventative mainte-nance program, including periodic inspection ofpacking, gaskets and seats is a key to reducingthe occurrence of these problems. Factors thataffect valve service life include but are not neces-sarily limited to, the following:

1. Selection of proper design and materials forthe intended service.

2. Frequency of opening and closing.3. Corrosive and/or erosive properties of the

contained fluid.4. Service pressure and temperature.5. Reasonable care in operation (e.g., avoidance

of overtightening of the handwheel).6. Degree of leakage, if any, that the user’s

system can tolerate.7. Proper installation and maintenance,

For specific recommendations on maintenanceor service consult Pacific Valves.

1. Bolts should be progressively tightened in a star pattern to prevent cocking of the flange and uneven gasketpressure.

2. Torque values listed are typical or alloy steel bolts (approximately 100,000 psi yield strength) used with carbon orintermediate alloy steel valves.

3. Final torque required to pull up joint may vary greatly due to effects of temperature, corrosion, lubrication and threadfinish.

4. Torque requirements for a given bolt diameter may not be the same when used on valves of different material orspecial design. For best results consult Pacific Valves for recommendation.

Storage

If valves are not put into service within threemonths after factory shipment, long term storagemeasures should be initiated to preclude valvedeterioration. Contact Pacific Valves for detailsregarding long term storage procedures.

Installation

HANDLING—Valves should always be installedin clean lines. Use lifting lugs where provided. Iflugs are not provided, slings should be used.VALVES MUST NEVER BE LIFTED BYHANDWHEELS OR STEMS.

WELD END VALVES—Weld end valves shouldbe installed using proper welding practices simi-lar to procedures covered in ANSI B31.1 throughB31.8. Care must be taken not to overheat valvebodies. Temperatures exceeding 400°F in theseat area of the valves during welding may causeseat distortion and leakage. During the weldingoperation, the valve should be assembled and inthe closed position for maximum support andprotection of seating surfaces. Weld debris shouldbe cleaned from line and valve internals beforeoperating valves.

Maintenance

FLANGED BONNET JOINT—Valve bonnet jointsare assembled to design specifications at thetime of factory assembly. However, because ofthe flexible nature of joint materials, varying appli-cations can affect bolt stress and cause bonnetleakage problems. Internal pressure, tempera-ture and external piping loads can affect thebonnet seal and certain precautions must betaken to prevent joint leakage. Line pressuretends to relieve gasket loads during operation. Allbolted joints should be inspected periodically andretorqued as needed.

Factory assembly takes place at ambient tem-peratures. However, many actual service condi-tions are at elevated temperatures. For condi-tions where bolting creep (elongation understress—increasing with higher temperatures) canoccur, it is recommended that bonnet bolting beretorqued after the first shutdown of the system.For services over 500°F, retorque bolts duringthe first 100 hours regardless of whether or notshutdown has occurred.
