Carbon Steel DBB Trunnion Ball Valve, 32 IN, 300 LB, Flanged

Designed to comply with API 6D and BS 5351 standards, this DBB trunnion-mounted ball valve delivers reliable isolation for critical pipeline applications. The carbon steel ASTM A105N body provides high strength and pressure resistance, while the F316 stainless steel trim ensures excellent corrosion performance and durability. Sized at 32 inches (DN800) and rated for Class 300 LB / PN50, the valve features RF flanged ends for secure, leak-tight installation. Gear operation allows smooth, controlled actuation with minimal torque. As a leading DBB trunnion ball valve supplier from China, we provide robust, precision-engineered valves for demanding industrial service.
