pdf GW 300 Pressure Control Valve

GW 300 Pressure Control Valve
This valve is used where a controlled constant pressure is required for a downstream wet system - e.g. water supply to fire hydrants. The valve provides an alarm signal via TP5 port when activated. The valve has no actuator. During set-up (commissioning) the downstream pressure is pumped slightly higher than the pilot set-pressure setting, which will lock the deluge valve closed. In case of a downstream pressure drop the C-300 Pressure Control valve will open and start regulating.
