Key Specifications / Features

As a leading manufacturer of API 6D dual plate check valves in China, we specialize in 42-inch, Class 300 LB non-return valves made from ASTM A351 CF8M stainless steel with wafer connections. These spring-loaded, one-way valves are designed to prevent backflow in pipelines. Featuring a one-piece body, a central pin, and two spring-loaded plates, they allow fluid to pass in the flow direction and block it when flow reverses. Compared to conventional swing check valves, our dual plate check valves significantly reduce weight and length, saving cost and space in piping systems.
