10 Inch DBB Ball Valve, API 6D, A182 F55, CL900, RTJ Flanged

This trunnion-mounted ball valve is designed and manufactured in accordance with API 6D standards, ensuring dependable performance in high-pressure and critical service applications. The valve body is forged from ASTM A182 F55 super duplex stainless steel, offering exceptional mechanical strength and superior resistance to corrosion, pitting, and chloride stress cracking. With a size of 10 Inch (DN250 / 250 mm) and a pressure rating of Class 900 LB / PN150, it is well-suited for demanding oil & gas, petrochemical, and offshore environments. RTJ flanged ends provide secure, leak-tight sealing under high-pressure conditions, while the LF2 + ENP trim enhances durability and wear resistance. As a leading DBB Ball Valve Supplier in China, we provide precision-engineered valves for global industrial projects.
