It is designed to automatically enable and disable the pump without damaging the system and is connected in series with the system. The valve opens with the pump and closes after the pump when the system is shut down to prevent pressure fluctuations during opening and closing. At the same time, it can be used as a hydraulic check valve with control devices such as valve control devices, time relays, switches, and PLC control units.
