We are a specialized manufacturer of wafer check valves. The center vertical pin shaft ensures proper alignment. When the valve is open, the resultant force of the fluid acts on the center of the sealing face of the disc, while the point of action of the counter spring support force is on the center of the disc surface. This design allows the root of the disc to open first, avoiding the wear on the sealing surface that is common with conventional valves. This feature enhances the durability of the valve seal. The wafer check valve is a type of valve that automatically opens and closes based on the flow of the medium itself and is used to prevent reverse flow of the medium.
