H76X Wafer Butterfly Check Valve

H76X Wafer Butterfly Check Valve Structure
H76X Wafer Butterfly Check Valve Structure

Scope of application

H76X Wafer Butterfly Check Valve is composed of valve body, disc, valve stem and spring, etc. It is connected by wafer. Due to the short closing stroke of the disc and its spring loading, water hammer can be significantly reduced. The valve is mainly suitable for urban, industrial and high-rise building water supply and drainage pipe networks. Because its structure length is shorter than that of general check valves, it is most suitable for places with limited installation space.
