We are a specialized manufacturer of wafer check valves featuring a unique center vertical pin shaft design. When the valve opens, the resultant force of the fluid acts on the center of the disc's sealing face, while the counter spring support force is applied to the center of the disc surface. This design ensures that the root of the disc opens first, preventing wear on the sealing surface, unlike traditional valves. The wafer check valve operates automatically, opening and closing based on the flow of the medium, and is used to prevent reverse flow.
