Powers #11 Regulators

With Powers #11 Self-Operating Temperature

Regulators, you no longer need external power to

control your process. Just one temperature set-point

adjustment to make and the rugged, self-operating

#11 Regulator controls the flow of heating or cooling

medium and maintains a uniform temperature.

So whether you’re using processing equipment, heat

exchangers, or machinery, Powers #11 Self-Operating

Temperature Regulators are the easy solution to your

control problems.

Component SystemThermal System Options

Powers No. 11 Regulator capability includesinterchangeable sensing and control “components” forminimum downtime, greater flexibility, and extra economy.Any of 29 thermal systems (composed of remote bulb,capillary, and bellows) can be teamed up with 35 standardvalve assemblies. This means approximately 1,000 standardmodels are available to meet virtually every processrequirements.

If a thermal system is damaged—or if process changesrequire a different temperature range—replacementcan be made in minutes without removing the valveassembly from the supply line. Similarly, asingle thermal system can accommodatea variety of valve types and sizes.

The Thermal System is the keycomponent of a #11 Regulator. Itsenses the process temperature andprovides power to stroke the valve.The #11 Thermal System offerstremendous flexibility through its widerange of options.

Application: The #11 DoubleSeat Regulators are normallyused in applications where singleseat regulators do not haveenough capacity. Double SeatRegulators do not have tightshut-off (when new, leakage= 0.5% of max. flow), andshould not be used whereleakage can cause over-heating in low capacityheating systems (e.g. HeatExchangers). Double SeatRegulators will work well inheating systems that havestorage capacity (e.g., tanktype water heaters, orconstant flow heat exchangersystems with storage tanks)and are excellent for coolingapplications which usuallyutilize some additionalmethod of bypassing wateraround the #11 Regulator.

Sensing Bulbs and Protective WellsBulb size is usually dictated by range and valve type selected. Refer to “How to Order” information on pages22–23 for proper bulb size.

Style D—Fixed Union Bulbs (Standard)For rigid, pressure-tight attachment to vessel or pipeline—either directly or into socket well (see Style S wells).Union connection simplifies installation.

Style J—Plain Bulb (Special)No union—for liquid or air immersion in open tanks or ducts. Maximum 15 foot coated capillary length.

Style A—Adjustable Union Bulb (Special)For pressure-tight insertion into tanks or ducts. Adjustable union permits capillary to be moved any desireddistance through fitting and into liquid for more effective sensing bulb position.

Style G—Finned Bulb (Special) Kit may be added to style “D” bulb as noted.

For air-sensing applications not corrosive to copper. Has duct-mounting flange for easy installation. Flangerequires 31⁄4″ dia. bolt circle; four 9⁄32″ dia. bolt holes at 90° spacing.

Style S WellsFor sealing Style D bulb in tanks or pipeline installation. Provides higher pressure rating and corrosion protectionfor bulb.

Notes: (1) Teflon-coated bulb and capillary is resistant to deterioration in most metal-finishing baths and other chemical solutions at temperatures to 400°F max.(Refer to Powers Form AE-14 for information on corrosive resistance of specific solutions.)(2) Pressure ratings are valid up to following temperature limits: 270°F for all copper bulbs and wells; 600°F for all others.

#11 Regulator Sizing

Valve SizingThe following sizing tables apply for steam or water input. Forother media, capacities may be calculated using CV factors—or consult factory. To prevent cycling, valve size should notexceed supply line size; preferably, it should be one or twosizes smaller.

Maximum Operating Pressure DifferentialA pressure drop (differential) for fluid flow must exist acrossthe valve. Pressure differential is the difference in pressurebetween inlet and outlet under flow conditions. Thegreater the differential, the greater the flow at any plugposition.

For steam, maximum flow occurs at a drop equal to approxi-mately 50% of absolute supply pressure (gauge pressure + 15 psi). To size properly, it is necessary to know availabledifferential at maximum flow. For best control, as muchdifferential as possible should be taken across the valve. Forwater, use a pressure drop of at least 25% of inlet pressure.

Caution: Do not exceed maximum differentials for valve size shown in tables on pages 19–22. Too large a differentialmay cause valve “chatter” or prevent shutoff. The maximumdifferential is the pressure the valve will have against it atshutoff.

The following water capacities of Powers#11 Regulator 3-way valves are based onpiping as shown. The cold water supply linemust be connected to the upper inlet “U”.Hot water supply must be connected tobottom inlet “B”. Side port “C” is the outletfor the mixed water.

Note: 3-way regulators perform poorly withless than 8 lb. pressure differential.

Tempered water systems should employdownstream high temperature limit controls(Powers AquaSentry) to protect users fromscalding in the event of regulator failure.
