We are a specialized manufacturer of wafer check valves, featuring a unique center vertical pin shaft design. When the valve is open, the resultant force of the fluid acts on the center of the sealing face of the disc, while the counter spring support force acts on the center of the disc surface. This design ensures that the root of the disc opens first, preventing wear on the sealing surface that is common in conventional valves and enhancing the durability of the valve seal. The wafer check valve operates automatically, opening and closing based on the flow of the medium itself, and is specifically designed to prevent reverse flow of the medium.
