Key Specifications / Features
Built for demanding high-pressure service, this DBB Trunnion Ball Valve is engineered in compliance with BS 5351 and API 6D standards, ensuring reliable performance in critical pipeline systems. The valve body is manufactured from ASTM A182 F53 super duplex stainless steel, delivering outstanding strength, corrosion resistance, and long-term durability in harsh environments such as offshore, oil & gas, and chemical processing. Sized at 8 Inch (DN200 / 200 mm) and rated Class 900 LB / PN150, it features RTJ flanged ends for secure, leak-tight connections under high pressure. The gear-operated mechanism provides smooth, precise operation and reduced torque requirements. As a leading DBB Trunnion Ball Valve Factory in China, we deliver high-quality, precision-engineered valves for global industrial applications.
