Lined Vertical Check Valve

The function of this type of valve is to only allow the medium to flow in one direction, and to prevent the flow in one direction. Usually this kind of valve works automatically. Under the action of fluid pressure flowing in one direction, the valve flap opens; when the fluid flows in the opposite direction, the fluid pressure and the self-coincident valve flap of the valve flap act on the valve seat, thereby cutting off the flow.
