S&W Dual Plate Check Valve

The S&W Dual Plate Check Valve is a compact, energy-efficient non-return valve designed to prevent backflow in liquid and gas pipelines. It features two spring-loaded plates (discs) that open with forward flow and close tightly upon flow reversal, minimizing water hammer and pressure loss. Commonly used in power plants, oil and gas facilities, water treatment, and HVAC systems, it is engineered for horizontal and vertical installations.
