INTRODUCTION

This guide is designed to assist you in selecting valves for yourapplication. It provides procedures and provides the information foryou to choose an appropriate valve. It includes a valve sizingreference tool. The tables and figures contained herein provide aconvenient method for CVcalculation, valve and actuator selection;

if you prefer to use equations, they are provided in the Appendix.

SUMMARY OF THE VALVESELECTION PROCESS

Check the glossary (located in the back of this guide) for a definitionof terms that are unfamiliar to you. The need for properly sized valvescannot be overemphasized. Good control, economic operation, andlong equipment life are the benefits of proper valve sizing. Anoversized valve cannot control properly, and, if too large, cannotcontrol at all. At the same time, a valve that is too small will notprovide adequate flow.

IMPORTANTThe first step in selecting a valve is to determine themedium (water or steam).

Selecting Water ValvesThere are four more steps to choosing an appropriate water valve:

1. Determine the water medium temperature, pressure, and thepressure drop across the valve. (The valve pressure drop shouldbe equal to or greater than the pressure drop through the coil orradiator, plus the pipe and fittings connecting them to thesupply and return mains.)

2. Using this information and Table 2, calculate the required CVand/or pipe size.

3. Establish the required valve body configuration for theapplication. This is typically fixed by the particularapplication and often is included in the design specifications.Standard body configurations are: Two-way

Straight-through Angle Body

Three-way Diverting Mixing

4. Find the appropriate table (see the Quick Reference Guide,on the inside front cover). Follow the table, starting at theleftmost column. Proceed across the table until a specificvalve O.S. Number is selected.

NOTES: The calculated CVwill rarely match the CVof an availablevalve. Select the valve with the closest CVvalue. For

example, if the calculated CVis 87, and the two closest CVvalues are 63 and 100, the best choice would be a valvewith a CVof 100.

In general, water valves require equal percentage flow.Determine the composition of the medium. (Is a water/glycol solution required?) This is an important stepbecause glycol solutions may preclude using some valves.See Tables 3-8 for valves compatible with glycol solutions.

Selecting Steam ValvesThere are five more steps in choosing the appropriate steam valve:

1. Determine the steam medium temperature, pressure, and thepressure drop across the valve. (This is often determinedusing inlet vs. outlet pressures; for example: a valve with a75 psi inlet and a 50 psi outlet would have a pressure drop of25 psi.)

2. Using this information (and Tables 10 and 11), calculate theCVor select the pipe size.

3. Check the average pressure and the temperature to determinethe quality of the steam medium. The quality of the steam is: Saturated SuperheatedDetermining the quality of the steam is important becausesuperheated steam can preclude using some valves. Steam issuperheated (and can require a valve with a larger C

V) when

the temperature exceeds the boiling point noted in Propertiesof Saturated Steam (see inside back cover) for the averagepressure in question. The difference between the twotemperatures is the amount of superheat. Use the followingequation to determine the correct C

Vto use:

C C SV VCalculated= + [ ]1 0 0007( . )Where: S = superheat degrees (in Fahrenheit).

4. Establish the required valve body configuration for theapplication. This is typically fixed by the particularapplication and is often part of the design specifications.Standard body configurations are: Two-way

Straight-through Angle Body

NOTE: There are nothree-way steam valves.

5. Find the appropriate table (see the Quick Reference Guide,on the inside front cover). Follow the table, starting at theleftmost column. Proceed across the table until a specificvalve O.S. Number is selected.

NOTES: In general, steam valves require linear flow.

The calculated CVwill rarely match the CVof an availablevalve. Select the valve with the closest CVvalue. Forexample, if the calculated CVis 87, and the two closest CVvalues are 63 and 100, the best choice would be a valvewith a CVof 100.

GENERAL CONSIDERATIONSFOR SELECTING VALUES TOCALCULATE CV.

Factors that apply to all valve selections include control sensitivity,pressure drop, and closeoff.

IMPORTANT

Factors vary for valve selection when the valve to be usedis a ball valve. If you plan to use a ball valve, be sure to

read the Ball Valve Application Notes section.

Control SensitivityThe control sensitivity is a measure of how well a valve performs inthe system. Ideally, the control system as a whole should have linearcontrol over its entire operating range; for example, a small increase intemperature should result in a small increase in cooling. Nonlinearsystems can cause a large increase in cooling with a small increase intemperature.

For a valve, the primary factor in control sensitivity is the flowcharacteristic. Steam applications usually require valves with linearflow characteristics, whereas hot water applications generallyrequire valves with equal percentage flow characteristics. In thecase of chilled water applications, the proper flow characteristicdepends on how close the water temperature is to the ambient airtemperature. For chilled water, the two temperatures are generallycloser together, and the flow characteristic should be linear.

Pressure DropThe pressure drop (or P) is the available pump pressure differentialbetween supply and return. It is calculated using the design flow atthe valve location. The pressure drop across the valve must be largeenough so that, as the valve starts to close, it diminishes the flow.

Generally, the desired pressure drop is the largest available becauseit provides the greatest resolution of control.

If the valve is oversized, the pressure drop will be too low. Thiscreates a situation in which the valve only needs to open slightly to

allow almost 100 percent flow. So, when the controller calls for asmall amount of heat, the valve opens a small amount, allowing toomuch flow. As a result, the controller signals to decrease the amountof heat and the valve closes completely. With the heat shut off, thecontroller calls for heat again and the cycle, often called hunting,continues.

One exception to the concern about oversized valves is the two-

position valve; because a two-position valve is either open orclosed, it is not important if the valve is slightly larger thannecessary. See Fig. 1 for information on heat output, flow and stemtravel characteristics.

CloseoffThe closeoff rating of a valve is the amount of force required for thevalve to close off against the existing flow. There are several valvesdesigned for applications where tight closeoff is not required; in otherwords, leakage through the valve is not an issue. Many applications donot allow for such a situation and the desired closeoff is tight. Becertain to choose the appropriate valve for the application. Valves notrated for tight closeoff are flagged in both the valve specification tableand the valve/actuator compatibility table.

IMPORTANT

In applications where valve closure failure is hazardous,the maximum upstream pressure must not exceed thecloseoff rating, regardless of downstream pressure.

BALL VALVE APPLICATION NOTES

Ball valves with very small ports, such as the VB30A1005 are mostsuitable for on/off control. If modulating control is required at small

CVcapacities around 1, a globe style valve may be a better choice.

EFFECTIVE CVValves mounted using pipe reducers decrease the capacity. The CVvalues in Table 1 must be used to size valves when pipe reducers arused; for example, a VB30A1088 (1-1/4 in., reduced port valve)used with 1-1/4 in. piping, results in a CVof 48. However, the samevalve mounted to 2 in. piping pipe reducers, results in a CVof 38.

All Ball ValvesBecause of the inherent high capacities of ball valves, pipe reducers

are almost always necessary. A valve mounted between pipereducers has a decreased capacity because of the pressure lossinduced by the reducers. To determine the proper CV data for valvesizing when reducers are required, see Table 1.

Unlike globe valves, differential pressure across a ball valve has anegligible effect (at typical hydronic system pressures) on theactuator force required to close the valve.

Two-way valves are shipped from the factory in the normally openposition. Three-way valves, normally open (as shipped from thefactory) is with flow from the side (inlet) port to the cast port (seeFig. 2).

WATER VALVE SELECTION

Selecting Control TypeThere are two control types that can be used, two-position (open/closed) and modulating (proportional).

Two-PositionA two-position valve can be sized using two methods. Method oneuses the actual pressure in the line when calculating the pressuredrop to minimize the drop. However, it is sometimes advantageous,or even required, to size a valve based on the pipe size. This is thesecond method, which determines the valve size for easyinstallation, because it is line sizedor the same size as the pipe. Todetermine which method is appropriate, consider that the pressuredrop and flow rate determine the life of the valve. A pressure dropthat is too large causes noisy valve operation and decreases the life-span of the valve. However, if the valve size is significantlydifferent from the piping, it will be difficult to install properly.

The rule of thumb when sizing two-position, two-way water valvesis to use 10 to 20 percent of the minimum difference betweensupply and return pressure at design operating conditions as thepressure drop. (This drop is typically between 2 and 5 psi.)

ModulatingModulating valves can be either two-way or three-way. Modulatingtwo-way valves typically throttle the flow of water to the load.Three-way valves can be mixing or diverting and have multipleapplications. When sizing a modulating valve, consider the pressurethroughout the valve travel. The pressure drop must be large enoughso that, as the valve starts to close, it can diminish the flow. If this isnot accomplished, the valve will not be able to maintain controlthroughout its entire range of travel. However, a pressure drop thatis too large causes noisy valve operation and decreases the life-spanof the valve.

Two-waySelect a two-way water valve for a pressure drop of 50 percent ormore of the controlled load. If the pressure is difficult to calculate,the normal procedure is to use a drop at least equal to the drop inthe coil (or other load being controlled) unless small booster pumpsare used. For secondary lines with small booster pumps, 50 percentof the available pressure difference (equal to the load drop or 50percent of the booster pump head) is the pressure drop to use.

Three-way

Select three-way water valves for a variety of applications. Three ofthe most common applications follow.

For coil bypass applications, use mixing valves. The recommendedpressure drop is 50 to 70 percent of the minimum differencebetween supply and return pressure at design operating conditions.

For mixing valves in boiler bypass applications, the recommendedmethod for determining pressure drop is:

1. Determine the design pressure drop through the boiler,including all piping, valves and fittings from the bypass con-nection through the boiler and up to the three-way valve input.

2. For accurate control results select a valve with a pressuredrop equal to or greater than this drop.

3. Optional: A manual balancing valve can be installed in theboiler bypass to equalize boiler drop and bypass drop.

Diverting valves are typically used to create a load bypass. The valveaccepts water from the supply and then throttles flow to the load,discharging the excess through a bypass line that connects with thereturn from the load. These valves control output the same way astwo-way throttling valves, and must be selected using the same highpressure drops to obtain accurate control results. Usually, the pressuredrop in a diverting valve equals the maximum value of the inletpressure minus the minimum value of the downstream pressure.

Calculating CVTo determine the appropriate CVrating, one must know:

Valve differential pressure (p)Flow rate (gpm)

Using these two values and Table 2, determine the calculated CVvalue for the application.

EXAMPLE: The job specifications require a three-waymixing valve with a flow rate of 225 gpm anda differential pressure of 15 psi. The value onthe chart that corresponds to these is 58.1.When control type and CVare known, seeTables 3 through 8 to select your valve. Thetwo CVratings around this value from Table 7are 40 and 63 (for a three-way valve). Becaus40 is too small, a valve with a CVof 63 (suchas the V5013B1003) must be used.

In most cases, including the above example, the required CVfallsbetween two valve sizes. If the pressure drop associated with the

smaller valve is acceptable for the application, select the smallervalve; otherwise, use the larger valve. More than likely, asillustrated in the above example, the larger valve must be used.

Finalize Valve SelectionOnce the Control Type and CVare known, the appropriate valve canbe selected using Tables 3 through 8. Prior to finalizing a valve choiceverify suitability by comparing job requirements to existing valvespecifications. If the initial selection does not meet the requiredspecifications, check the table again for an appropriate valve.

EXAMPLE: If you chose the V5013B1003 (as noted in theabove Calculating CVexample), but the jobspecifications require a three-way mixing valvewith an equal percentage flow characteristic, it

will not work because it has a constant totalflow characteristic. However, the V3361E2007has an equal percentage flow characteristic andalso meets the other requirements.

STEAM VALVE SELECTION

Selecting Control TypeAll steam valves are two-way valves (except for the V5086B, whichis a single-port, thermostatic actuated steam valve). There are twovalve operations control types, two-position (open/closed) andmodulating (proportional).

Two-PositionTwo-position steam valves are typically selected based on the pipesize of the line; for example, if the pipe size is three inches indiameter, you would select a three inch steam valve.

ModulatingTwo-way modulating steam valves are typically used to throttle theflow of steam in proportion to the load. Similar to water valves, whensizing a modulating valve for steam, consider the pressure throughoutthe valve travel. The pressure drop must be large enough so that, as thevalve starts to close, it can diminish the flow. If this is notaccomplished, the valve is not able to maintain control throughout itsentire range of travel. However, a pressure drop that is too large causes

noisy valve operation and decreases the life-span of the valve.

Calculating CVTo determine the appropriate CVrating, one must know:

Return Pressure (Bar)

Using the supply pressure, differential pressure and Table 10,determine the value of Factor A for the application. Then using FactorA, the flow rate and Table 11, determine the CVfor the application.

IMPORTANT

If the steam is superheated, it can require a valve with alarger CV. Steam is superheated when the temperatureexceeds that noted in Properties of Saturated Steam section

(inside back cover) for the given average pressure. If this isthe case, the difference between the two temperatures is theamount of superheat. Use the following equation todetermine the correct CVto use:

C C SV VCalculated= + [ ]1 0 0007( . )Where: S = degrees of superheat (in Fahrenheit).

EXAMPLE: The job specifications require a direct acting two-way valve with a supply of 30 psi, a pressuredrop of 5 psi and a flow rate of 4000 lb/hr. With asupply of 30 psi and a return of 25 psi, Table 10provides 1.5 as the value of Factor A. Then, using1.5 and the flow rate of 4000 lb/hr, the value fromTable 11 is 94. The two CVratings from Table 12

around this value are 63 and 100. Because 63 istoo small, a two-way valve with a CVof 100(such as the V5011G1129) must be used.

In most cases, including the above example, the calculated CVfallsbetween two valve sizes. When this happens, use a valve with the nexthigher CVvalue unless the calculated CVis within 10 percent of thenext lower CVvalue.

Table 11. Steam valve CVfinal calculation.

Finalize Valve SelectionWith the Control Type and CVknown, select the appropriate valveusing Tables 12 through 15. Prior to finalizing a choice, verifysuitability by comparing job requirements to existing valvespecifications. If the initial selection does not meet the requiredspecifications, check the table again for an appropriate valve.

EXAMPLE: If you chose the V5011G1129 (as noted in theabove Calculating CVexample), but the jobspecifications require a two-way valve with anequal percentage flow characteristic, theV5011G1129 will not work because it has amodified linear flow characteristic. However,the V3351A3006 and V3451A3005 both havean equal percentage flow characteristic. Thechoice between them depends on the ANSI(pressure) rating requirement.

Default PositionThe default position of the actuator (also referred to as the state ofrest) is what determines whether the valve functions as normallyopen or closed. In its default position, the valve is normally open orclosed, depending on the valve body and the actuator. For example,a direct acting actuator used with a direct acting valve bodyproduces a normally open valve. But, if a reverse acting actuatorwere used with the same valve body, the valve would be normallyclosed. (See Valve Directional Notation for guidelines.)

Converter control valves should be normally closed and outdoor airpreheat valves should be normally open.

Actuator ForceDifferent actuators are capable of providing different amounts offorce with a given valve. The various closeoff ratings are detailed inTables 16 through 19. Once you have selected a valve, proceed withthe following process for selecting an actuator:

1. Find the matching valve size and CVwithin the valve family.2. Follow that row across to either the pneumatic or electric

section.3. Within that section, find the closeoff rating (the numbers in

the table) that is closest to the required closeoff rating.

IMPORTANT

If the application requires a tight closeoff, choose a ratin

that is greater than the required closeoff value.

4. Now, follow the column up to find the appropriate actuatortype (and, if necessary, linkage).

ACTUATOR SELECTION

When selecting an actuator to power the valve, the primary factorsare connectivity, default position, and actuator force. In short, theactuator must be able to connect to the valve (directly or with alinkage) and it must also be able to close the valve with enoughforce to provide closeoff capability.

There are many valve-actuator combinations where the actuator isdescribed as integral (or as a powerhead). Table 15 contains lists ofsteam valves that come with an integral pneumatic actuator. Thesevalves and actuators are designed to be used together and, therefore,are supplied as a unit. No additional pieces are required and there isno actuator selection involved, once a valve is selected.

ConnectivityThere are three primary types of connectivity with valve actuators.The first is integral, which is discussed above. The second, similarto integral, is direct coupled. These types of actuators, such as theMP953 or ML7984, are designed to be used with several differentvalves and require no extra linkage that is not part of the actuator.These are tagged as direct coupledin Tables 16 through 19. The

third type is the foot-mounted. These actuators require an addedlinkage, usually a Q5001. The linkage is mounted to the valve andthen the actuator is mounted to the linkage. One advantage of thisarrangement is that a variety of actuators and linkages can be used,allowing a larger range of closeoff values for a given valve.
