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 directly 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. This design ensures that the disc opens from its root first, effectively reducing wear on the sealing surface compared to conventional valves. As a result, the durability and reliability of the valve seal are significantly enhanced. The wafer check valve operates automatically based on the flow of the medium itself, preventing reverse flow. This makes it an essential component in various fluid systems, ensuring smooth and efficient operation while maintaining system integrity.
