For Chlorine, Sulfur Dioxide and Ammonia
The Super’ Series 71P11 Gas Pressure Reducing & Shut-off valve is a diaphragm type gas pressure-regulating valve designed for use on chlorine Sulfur Dioxide or 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, the gas flow will be shut off.71PI101 L Manual, 71P1102L Pneumatic, 7IP1103 L Electric.All models are constructed with materials resistant to corrosion from gases being controlled.
