The piston type multi -function pump control system Is the intellient valve installed In the outlet of the pump outlet of the large- -caliber water supply pipe network, preventing the backflow of the medium, waiter hammer and water hammer, The valve has three functions of electric valve, reverse stop valve and water hammer eliminator,which can effectively improve the safety and ability of water supply system.
Double Chambers and double disc structure can make the valve after the pump stopped quickly closed90% (to prevent the back flow medium pump inversion), and then aiowly Closing the remaining 10% (eliminate destructive water hammer) piston valve ls reliable In performance, high strength, smooth movement, prevent pumping water hammer and 8top the pump water hammer, The valve can automatically realize the opening and closing according to the operating procedures of the pump motor, and the discharge volume and pressure loss are small.
This valve is used mainly for water supply and drainage system and can be set on the pump outlet to prevent the pump from getting harmed the medium back flow. it can also be set on the mouth of a water outlet pipe to prevent the medium from backflow.
Simple structure, reliable performance, long durable, open-close times can be up to over million ones, suitable for sewage.
