Lined Diaphragm H76 Duel-plate Check Valve

The valve is connected by a pair of clamps, and the structure is tight. Because of the short closing stroke and spring yellow loading, the closing speed is fast, which can significantly reduce the water hammer phenomenon. The valve has the characteristics of small volume, light weight, sensitive action, reliable sealing, convenient installation, etc. It can be installed horizontally or vertically. The fully lined structure ensures the strong corrosion resistance of the spring, which can be applied to all kinds of strong corrosive medium products except tower melting metal and element fluorine.
