The Capital Controls® Series 71P11A Gas Pressure Reducing and Shutoff Valve is a diaphragm-type gas pressure regulating valve designed for use on chlorine, sulfur dioxide and ammonia gas service. The valve is used in a gas dispensing system to prevent liquefaction of the gas by providing a controlled pressure drop in the piping system.
Downstream pressure is regulated to a reduced value by adjustment of the control setting. If the downstream pressure exceeds the pressure at which the valve is set, gas flow will be shut off.
There are three models for use with a variety of control applications:
- 71P11A_01 Manual
- 71P11A_02 Pneumatic/hydraulic
- 71P11A_03 Electric
