Newsway Valve Company Dual Plate Check Valve opening and closing parts rely on medium flow and force to open or close by themselves, in order to prevent the back flow of the medium valve is called check valve. Check valves belong to the category of automatic valves, which are mainly used for pipelines with one-way flow of medium, and only allow medium to flow in one direction to prevent accidents.

Check valve is a valve that can automatically prevent the backflow of fluid. The valve flap of the Dual Plate Check Valve opens under the action of fluid pressure, and the fluid flows from the inlet side to the outlet side. When the pressure on the inlet side is lower than the outlet side, the valve flap automatically closes under the influence of the fluid pressure difference, its own gravity and other factors to prevent the fluid from flowing back.
