The Wafer Single Disc Check Valves, also known as single check valve and check valve, is a valve which can automatically prevent fluid from backflow. The disc of the check valve is opened under the action of fluid pressure, and the fluid flows from the inlet side to the outlet side. When the inlet side pressure is lower than the outlet side, the disc automatically closes under the influence of fluid pressure, gravity and other factors to prevent fluid backflow. It can be installed horizontally or vertically. The vertical installation should pay attention to the water flow from bottom to top. When installing, pay attention to whether the installation direction is correct.

The function of the Bronze Wafer Check Valve is to control the one-way flow direction of the valve in the pipeline, so as to prevent the backflow of the medium in the pipeline.
