Wafer Single Disc Check Valve
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.

Learn MoreRubber Lined Check Valve
The seat sealing surface of the Rubber Lined Check Valve can be used as body hardfacing material or lining rubber, which has wide application range and reliable sealing. For industrial, environmental protection, water treatment, high-rise building water supply and drainage pipeline, to prevent the reverse flow of media. The Rubber Lined Check Valve plate is two semicircle, and the spring is forced to reset. Because the force of the torsion spring usually is closed, when the fluid is moving forward, the pressure of the fluid turns the disc to turn around the hinge and the valve opens. Once the fluid flow stops, the valve is closed before reverse flow due to the action of the spring.

The Wafer Lift Check Valves consists of valve body, disc and spring. It is installed horizontally or vertically in the pipeline system to prevent the media from backstreaming. The valve has the advantages of short structure, small volume, light weight, quick closing of disc, small water hammer pressure, smooth flow passage, small fluid resistance, sensitive action and good sealing performance.
