We are a specialized manufacturer of wafer check valves. The valve features a center vertical pin shaft. When the valve opens, the resultant force of the fluid acts on the center of the disc's sealing face, while the counter spring support force is applied at the center of the disc surface. This design ensures that the root of the disc opens first. As a result, it minimizes wear on the sealing surface, which is common in traditional valves, and enhances the durability of the valve seal. The wafer check valve is an automatic valve that opens and closes based on the flow of the medium, effectively preventing backflow.
