HOW TO CHOOSE A REGULATORIf you already know the product that you want information on, find the product page in the Table ofContents. Pages showing popular combinations of Pilot and Regulators are found in the CombinationRegulators Chapter. Detailed product information on materials, ratings, dimensions, weights and applica-tions are found in the Products Chapters. All sizing information is contained in the Regulator Sizing Chapter.

If you are not sure of what you need, collect all the following information. You will need it to select the rightproduct for your needs.

Inlet Pressure

Flow Rate

Flow Media (i.e.: Steam, Water, etc.)

Desired Delivery Pressure

Noise Restrictions, if any

Type of Pilot Control (i.e.: Self Contained, Pneumatic, Electronic, etc.)

Application (i.e.: Temperature Regulation, Single Stage Pressure Regulation, etc.)

Application data is listed on each Product Page. If you identify the nature of the installation, it will assistyou selecting the proper equipment.

DIRECT ACTING OR PILOT OPERATED REGULATOR?You may be able to use a Direct Operated Regulator for your application. They are generally less expen-sive than Pilot Operated Regulators. However, they do not provide the same level of accuracy or rangeability.

If a Direct Acting Regulator is an option, consult the Direct Operated Valves Chapter to determine whichbest fits your specific needs. Then, consult the appropriate pages in the Regulator Sizing Chapter toselect the exact size you need.

If a Pilot Operated Regulator is required, go to Page __ (for Pressure Regulators) or Page __ (forTemperature Regulators). These selection charts will help you to quickly determine the type of productthat you need. The Pilot can be self contained, pneumatically or electronically actuated. Consult theappropriate pages in the Regulator Sizing Chapter to select the exact size Regulator and Pilot you need.Overall dimensions of the most popular combinations are provided in the Combination Regulators Chapter.

ECONOMICAL, ENGINEERED OR ENGINEERED WITH NOISE SUPPRESSION?The choice of how to size a regulator for an application is up to you. The most economical choice doesnot necessarily take into consideration the optimum loading of the Regulator, which could affect it’sservice life. Properly engineered Spence Regulators have been in continuous service for as much as 50years. In high pressure reduction stations, noise can be a serious environmental problem. Spence offersa number of Noise Suppression products to reduce this problem. You will find comprehensive noisereduction sizing and selection information in the Noise Reduction Chapter.

THE OPERATING CYCLE OF A SPENCE PRESSURE REGULATORThe basic Type ED has been selected to illustrate the operation of a SPENCE Pilot Operated Pressure Regulator.This presentation describes the successive steps in the mechanical cycle of the Regulator.

1MAIN VALVE is normally closed.On placing Regulator in service,

initial pressure fills the passagesshown in red.

3CONTROL LINE connectsPilot Diaphragm Chamber

to Delivery piping.

4ADJUSTING SPRING,when compressed,

forces Pilot Valve open.

5CONNECTING TUBINGconducts fluid from Pilot

to Main Valve Diaphragmand Bleedport. When Pilotopens, fluid flows throughPilot faster than it canescape at Bleedport, creatinga loading pressure (orange)which forces Main Valveopen.

6DELIVERY PIPE and Control Lineare now being filled with fluid

flowing through Main Valve.As delivery pressure (yellow) rises,

it overcomes the force exerted byAdjusting Spring and Pilot throttles.This , in turn, allows Main Valve tothrottle just enough to maintain theset delivery pressure.

If the demand ceases, Pilot closes,allowing the Main Valve to close –effecting a DEAD-END SHUTOFF.

THE OPERATING CYCLE OF A SPENCE TEMPERATURE REGULATORThe Type ET134 has been selected to illustrate the operation of a SPENCE Pilot Operated Temperature Regulator.This presentation describes the successive steps in the mechanical cycle of the Regulator.

1MAIN VALVE is normally closed. On placingRegulator in service, initial pressure fills the

passages shown in red.

3CONTROL LINE connects Pilot DiaphragmChamber to Delivery piping.

4PRESSURE SPRINGforces Pilot Valve open.

5CONNECTING TUBING conducts steam fromPilot to Main Valve Diaphragm and Bleedport.

When Pilot opens, steam flows through Pilot fasterthan it can escape at Bleedport, creating a loadingpressure (orange) which forces Main Valve open.

6HEATER, Delivery Pipe and ControlLine are now being filled with steam

flowing through Main Valve.As delivery pressure (yellow) rises, it

overcomes the force exerted by PressureSpring and Pilot throttles. This, in turnallows Main Valve to throttle just enoughto maintain the set delivery pressure.

7THERMOSTAT ELEMENT (vapor tension type) is connected into heater outlet.The rising temperature of the fluid (blue) being heated creates a vapor pressure

(green) on the Temperature Diaphragm. When this pressure has reached a pointsufficient to overcome the Temperature Adjusting Spring, it applies a force on theLever so as gradually to decrease the spring loading on the Pressure Diaphragm.This produces a stem-by-step reduction in the delivery pressure as the temperaturerises through several degrees.

If the desired temperature is exceeded, the vapor pressure on the PilotTemperature Diaphragm overcomes the forces of the Spring. This allows Pilot andMain Valve to close tight.

QUICK SELECTION CHARTFOR STEAM PRESSURE REGULATORS

Review the application data that you have collected. Consult the chart, starting with the inlet pressure that matches the inletpressure you have. Next, select your outlet pressure (reduced or delivery pressure). Then select the type of pilot control that youwill be using and, finally, the level of accuracy that your system requires. This will lead you to a recommended regulator. Please bear in mind that these recommendations are general in nature and you should check the Product Pages and Sizing Sectionto ensure you have selected the correct product. If you need assistance, contact your local Spence Technical Sales Representative.
