We are a specialized manufacturer of wafer check valves, known for their innovative design. A key feature is the 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 counter spring support force acts on the center of the disc surface, causing the root of the disc to open first. This design prevents wear on the sealing surface, which is common in conventional valves, and enhances the durability of the valve seal. The wafer check valve operates automatically, opening and closing based on the flow of the medium itself. It is specifically designed to prevent reverse flow, ensuring reliable and efficient operation.
