Key Specifications / Features
We specialize in supplying high-quality API 6D dual plate check valves, renowned for their efficiency and reliability. Our non-return valves, compliant with API 594, are constructed from ASTM A352 LCB material. Designed for 16-inch pipelines and rated for Class 600 LB, these valves are available with wafer or flanged ends to suit various installation needs. The spring-loaded design features a one-piece body, central pin, and two plates that pivot on the pin, allowing fluid to flow in one direction while preventing backflow. Compared to conventional swing check valves, our dual plate check valves offer significant weight and length reductions, resulting in cost and space savings for your piping system.
