QUICK RELIEF VALVE, TO AVOID WATER HAMMER
This valve protects pumps and pipes from pump startup and shutoff pressure surges due to power failure.
Pump off means valve normally closed. If pump starting cause pressure surge, the pilot smoothly opens the valve to limit pressure rising. Quick relief valve opens due to both pressure rises and falls, fully reducing any pressure fluctuation.
TYPICAL APPLICATIONS
To eliminate pumping electric power failures surge causing abrupt variations on flow speed and pressure.
