Key Specifications / Features
As a trusted API 6D Dual Plate Check Valve supplier from China, we provide API 594 compliant non-return valves made from ASTM A216 WCB, available in 2 inches and Class 300 LB, with spring-loaded, double flanged ends. These dual plate check valves are designed to prevent backflow in various applications, such as oil and gas pipelines, water treatment plants, and chemical processing. Note that these valves are not shut-off valves and are not piggable. Therefore, it is essential to install a shut-off valve in conjunction with the dual plate check valve to ensure complete flow control and system integrity. Our valves offer reliable performance and durability, making them an excellent choice for critical industrial applications.
