The Stainless Steel Dual Plate Wafer Type Check Valve is a space-saving, lightweight non-return valve. It features two spring-loaded plates hinged on a central pin. When flow starts, the plates open; when it stops, the springs snap them shut to prevent backflow and water hammer. Its wafer design fits between pipe flanges, making it much lighter and shorter than traditional swing check valves. Built from SS316, it is ideal for high-volume water, oil, and gas systems.
