We are a specialized manufacturer of wafer check valves. Our unique design features a center vertical pin shaft. When the valve is open, the resultant force of the fluid acts on the center of the sealing face of the disc. Meanwhile, the counteracting spring support force is applied at the center of the disc surface, causing the disc to open from its root first. This design prevents wear on the sealing surface, a common issue with conventional valves, thereby enhancing the durability of the valve seal. A wafer check valve is a type of valve that automatically opens and closes based on the flow of the medium itself. It is primarily used to prevent the reverse flow of the medium.
