700X pump control valve structure and purpose
It is used at the pump outlet to carry out an accurate open or close through the pilot control of the solenoid valve, and to prevent of the medium’s back-flow. When the pump is about to stop water supply, it is closed slowly by about 90% first to prevent both water hammer and water shock noise from being produced due to sudden stop of the pump. And when the pump stops completely, it is fully closed to prevent the pump from the water’s back flow so as to protect it effectively from counter movement due to the shock of the back-flow. 700X Pump Control Valve can prevent effectively of water hammer and water shock noise. It can move reliably and stably and be used for a long time. The solenoid valve can use either AC220V or DC24V power.
