KEY FEATURES:
Limits system pressure by relieving excess flow
Protect pump from the overpressure damaging and Slow closing to prevent water hammer
Easily adjustable pressure setting
WORKING PRINCIPAL:
1.The valve can maintain the pressure differential on both ends of a valve or pump at a set value. If equipped with a check valve, it will automatically shut down in the event of reverse flow. This valve maintain the pressure difference between the two systems, regardless how the upstream pressure changes and maintain a pressure differential across the group.
2.The pressure differential increases, the pilot valve is turned to the open position, the main valve open, the pressure differential will be reduced.
3.The pressure differential decreases, the pilot valve is turned to the close position, the main valve closes, the pressure differential will be increased.
