  • Product Profile

    Due to the short closing stroke of the valve flap and spring loading, the water hammer phenomenon can be significantly reduced. Mainly used in municipal, industrial and high-rise buildings for water supply and drainage network, due to its structure length is shorter than the general check valve, so the installation is convenient.

  • Design Feature

    1, the valve by the valve body, valve plate, valve stem, spring and other components, can be installed horizontally or vertically in the water and other media pipeline, to prevent backflow of pipeline media, due to the use of alloy steel manufacturing, a wide range of use, high temperature resistance, opening and closing sensitive, good sealing performance.


    2, with a variety of connection forms, clamping type, lug type, double flange type.


    3, the valve structure is simple, the structure length is short, is conducive to saving installation space, and has a good economy.
