We specialize in the manufacturing of high-performance wafer check valves, featuring a center vertical pin shaft design. This innovative structure ensures that the fluid force acts on the center of the disc's sealing surface, while the counter spring force acts at the center of the disc body. As a result, the disc opens from the root first, minimizing wear on the sealing surface, a common issue with traditional designs, thereby enhancing the valve’s sealing longevity. The wafer check valve operates automatically, opening and closing based on the medium’s flow, and is specifically designed to prevent reverse flow in pipelines. Its streamlined profile and efficient operation make it suitable for a wide range of industrial applications.
