ASTM A350 LF2 Trunnion Ball Valve, DBB, API 6D, 36 IN, CL900

Designed for high-pressure and critical service applications, this 36-inch (DN900) DBB trunnion ball valve is manufactured to API 6D and BS 5351 standards for reliable sealing and operational safety. It features a robust ASTM A350 LF2 carbon steel body for excellent low-temperature toughness and F6A trim for enhanced wear and corrosion resistance. Rated Class 900 LB with RTJ flanged ends, it ensures secure, leak-tight connections under demanding conditions. The trunnion-mounted design reduces operating torque, while the precision gear operator provides smooth, controlled actuation. As a trusted DBB trunnion ball valve supplier in China, we deliver durable, high-performance valves for critical industrial systems.
