Product overview
DS101/201X piston type multifunctional water pump control valve is installed at the water pump outlet of large-diameter water supply pipe network system and is an intelligent valve to prevent medium backflow, water hammer and water hammer. The valve has three functions: electric valve, check valve and water hammer eliminator, which can effectively improve the safety and reliability of the water supply system. The double chamber and double disc structure can make the valve close 90% quickly after stopping the pump (to prevent the reverse rotation of the pump caused by the return medium), and then slowly close the remaining 10% (to eliminate the destructive water hammer). The piston valve has reliable performance, high strength and balanced action, so as to prevent the occasion of starting and stopping the pump water hammer. Just operate the start button of the water pump motor, and the valve can be opened and closed automatically according to the operating procedures of the water pump, with large flow and small pressure loss.
