We are a specialized manufacturer of wafer check valves. Our innovative design features a center vertical pin shaft. When the valve is open, the resultant force of the fluid acts directly on the center of the sealing face of the disc, while the counteracting spring support force is applied at the center of the disc surface. This ensures that the disc opens from its root first, reducing wear on the sealing surface compared to conventional valves and enhancing the durability and reliability of the valve seal. The wafer check valve operates automatically based on the flow of the medium itself, preventing reverse flow.
