Product overview

The wafer check valve is composed of valve body, valve disc, valve stem, spring and other parts. It adopts wafer connection. Due to the short closing stroke of the valve disc and spring loading, the water hammer phenomenon can be significantly reduced. This valve is mainly suitable for urban, industrial and high-rise building water supply and drainage pipe networks. Because its structure length is shorter than general check valves, it is most suitable for places with installation restrictions.
