This 6-Inch (DN150) Class 300 Trunnion Mounted Ball Valve is forged from ASTM A105 Carbon Steel, offering superior structural integrity and pressure-handling capability compared to standard cast valves. Designed for critical flow control in oil, gas, and petrochemical pipelines, the fixed ball trunnion structure minimizes operating torque and ensures bubble-tight sealing. Manufactured in accordance with API 6D, this valve is engineered to withstand the rigorous demands of high-pressure industrial applications.

🏭 Engineering & Compliance Highlights:

  • Material: Forged ASTM A105 Carbon Steel for high-pressure durability.
  • Structural Advantage: Trunnion-mounted design ensures stability in 6″ bore pipelines.
  • Compliance: Built to API 6D, ASME B16.34, and ASME B16.5 standards.
  • Service: Ideal for refined oil, natural gas, and general high-pressure process industries.
