Piston type multifunctional water pump control valve

Ds101 / 201x piston type multifunctional pump control valve is an intelligent valve installed at the pump outlet of large diameter water supply network system to prevent medium backflow, water hammer and water hammer. The valve has three functions: electric valve, backwater valve and water hammer eliminator. It can effectively improve the safety and reliability of water supply system. With double chamber and double disc structure, the valve can quickly close 90% after stopping the pump (to prevent the pump from reversing due to backflow medium), and slowly close the remaining 10% (to eliminate destructive water hammer). The piston valve has reliable performance, high strength and smooth action, which can prevent the pump from stopping when starting the pump. Just operate the pump motor on-off button and valve to automatically open and close in accordance with the pump operation procedures, with large flow and small pressure loss.
