Key Specifications / Features
Designed in accordance with BS 5351, this high-performance DBB trunnion-mounted ball valve features a robust ASTM A350 LF2 carbon steel body combined with F316 stainless steel trim, delivering excellent mechanical strength and corrosion resistance. Sized at DN65 (2-1/2 inch) and rated Class 900 LB / PN150, the valve is engineered for high-pressure service in demanding industrial systems. The RTJ flanged ends ensure reliable, leak-tight sealing under extreme conditions, while the gear-operated mechanism provides smooth, precise control and reduced operating torque. This valve is ideal for oil & gas, petrochemical, and high-pressure pipeline applications. As a leading DBB Trunnion Ball Valve Manufacturer in China, we deliver precision-engineered, reliable flow control solutions for global industries.
