Wafer Single Disc Check Valve

KOSEN Wafer Inclined Flap Check Valve, installed in the municipal, construction, steel, metallurgy, petroleum, chemical, food, medicine, power plant, water conservancy and irrigation and other fields of water intake, water supply, pressure, diving, sewage pumping room and oil, chemical fluid transportation system, melting electric valve, check valve and water hammer eliminator three equipment functions in one, It can effectively improve the safety and reliability of the system, meet the requirements of system automation control and energy saving.

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.
