We are a special 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.

Product Features

» Light and Compact: The wafer check valve is designed to be lightweight and compact, making it easy to install and handle, while also saving valuable space in various applications.
» Zero Leakage Sealing Design with Soft Seated: The valve features a zero leakage sealing design with a soft seat, ensuring a perfect seal and preventing any fluid leakage.
» Non-Slam Design: The valve incorporates a non-slam design, which prevents sudden closure, reducing noise and potential damage to the valve and connected piping.
» Bubble Tight Closure: The valve achieves a bubble-tight closure, providing a high level of sealing reliability and ensuring no backflow of the medium.
» Discs Open 85°: The discs open to an angle of 85°, which ensures a low pressure drop across the valve, optimizing flow efficiency and reducing energy consumption.
