Product Description

The function of the valve is to allow the medium to flow in one direction and prevent the direction from flowing. The valve operates automatically. Under the action of fluid pressure flowing in one direction, the valve disc opens. When the fluid flows in the opposite direction, the fluid pressure and the self-coincidence disc of the valve disc act on the valve seat, thereby cutting off the flow.
