Key Specifications / Features
As a leading API 594 Dual Plate Check Valve manufacturer in China, we offer non-return valves up to 48 inches, Class 150 LB, made from ASTM A890 4A duplex stainless steel with wafer or flanged ends. Our dual plate check valves are spring-loaded, one-way valves designed to prevent backflow in pipelines. Featuring a one-piece body, a central pin, and two spring-loaded plates, these valves allow fluid to pass in the flow direction while blocking reverse flow. Compared to conventional swing check valves, our dual plate design significantly reduces weight and length, offering cost and space savings for your piping system.
