Forged Check Valves

Forged check valves are the type of valves in which the opening and closing member is a circular valve flap and acts on its own weight and medium pressure to block the reverse flow of the medium. Check valves are to allow only the medium to flow in one direction and to prevent flow in the opposite direction. Usually, the valve is automatically operated, and the valve flap is opened by the fluid pressure flowing in one direction; when the fluid flows in the opposite direction, the fluid pressure and the self-reclosing valve flap of the valve disc act on the valve seat to cut off the flow.
Made of the premium materials, it is able to have strong frame to make sure the stable operation. And it is smooth with the delicate workmanship which is waterproof and resistant to corrosion, oxygen and dust. It is easy to maintain and clean, which can greatly prolong its service life.
