The valve is mainly used for water pump outlet of the water supply system, to prevent the media back, the phenomenon of water hammer and the water hammer, the valve combines electric valve, non-return function of three feet and water hammer eliminator, which can effectively improve the safety and reliability of water supply system, and the slow opening, fast closing, slow closing to eliminate the technical principles of integrated water hammer, to prevent water hammer and open the pump water hammer produced, only the operation of pump electric opening and closing, the valve can automatically according to the pump operating procedures of opening and closing, the valve, the pressure loss is small, reliable sealing performance, installation and maintenance, debugging convenience, long service life.

Note: the installation diagram of elastic valve seat seal or valve optional, suggest ≥ DN350 butterfly valve. The H value for reference purposes only, to the real actual size as.
