We specialize in manufacturing wafer check valves featuring a center vertical pin shaft design. When the valve is open, the fluid’s resultant force acts on the center of the disc's sealing face, while the counter spring support force acts at the disc's center. This design causes the root of the disc to open first, minimizing wear on the sealing surface, which is a common issue in older conventional valves. The wafer check valve operates automatically, opening and closing in response to the medium's flow, and is used to prevent reverse flow.
