Fig.622 wafer lift check valve is a single-disc, wafer-type valve designed for reliable and efficient flow control. It opens when the pressure or flow force exceeds the closing force, determined by spring tension, weight, installation position, and valve size. Once the force decreases, the spring automatically closes the valve, preventing backflow.
The compact wafer design significantly reduces weight compared to traditional valves, lowering transportation and installation costs while improving flexibility and efficiency.
Wafer-Type Design: Compact structure and lightweight, reducing transportation and installation costs.
Self-Centering Mechanism: Easy to install between flanges without additional alignment tools.
Low Pressure Drops: Ensures system efficiency and minimizes energy consumption.
Easy Installation and Maintenance: Simple to integrate into pipelines without complex maintenance procedures.
Vertical Pipeline Compatibility: Designed for vertical pipelines with downward flow.
Standard Metal-to-Metal Seat: Ensures reliable sealing under various operating conditions, with soft seat options available upon request.
Wide Flange Compatibility: Suitable for flanges conforming to CLASS150/300 and PN10/16/25/40 standards.
