Modular DBB Ball Valves, API 6D, A182 F304, 18 IN, CL900 LB

Trunnion mounted ball valve engineered in accordance with API 6D standards, featuring a fully welded construction with an ASTM A182 F304 stainless steel body and trim for excellent corrosion resistance and mechanical strength. This 18-inch valve, DN450 (450 mm), is rated for Class 900 LB service and supplied with RTJ flanged ends to ensure reliable sealing in high-pressure applications. The trunnion-mounted design reduces operating torque and enhances sealing stability, making the valve ideal for critical pipeline systems. As a leading modular DBB ball valves factory from China, we provide durable, high-performance solutions tailored to demanding industrial requirements.
