The valve has the functions of preventing backflow, starting the pump with light load, reducing water hammer, automatic control and remote monitoring. It is used at the outlet of centrifugal water pump, which can effectively prevent water hammer accidents in case of tripping and accidental power failure due to excessive starting current, and protect the safety of water pump and pipe network equipment.
The valve is an upgraded product of multi-functional water pump control valve. Its main functions and working principle are basically the same, but it has small volume, light weight, low resistance and low energy consumption. It is especially suitable for manufacturing large-diameter valves. The larger the diameter, the more obvious the advantages.
