GA diaphragm actuated pressure reducing valves are used to reduce a higher, fluctuating inlet pressure to a lower, steady outlet pressure regardless of variations in demand. The valve’s pilot system senses the outlet (downstream) pressure and modulates the main valve to allow enough flow to satisfy demand without letting the downstream pressure rise above its pilot setting. The valve will close drop tight during periods of zero demand to prevent over pressurization of the downstream system. GA diaphragm actuated pressure reducing valves can be supplied with additional functions such as solenoid shutoff, sustaining and/or check as well as other optional features. See individual Data Sheets for details.
