14″ DN350 PN16 CF8 Stainless Steel Trunnion Ball Valve (Gear Operated) | BSO Ballseal

Engineered for large-scale industrial pipelines, this heavy-duty DN350 (14 Inch) PN16 Trunnion Mounted Ball Valve features a robust CF8 (304) Stainless Steel construction and is equipped with a high-torque manual gear actuator for smooth, precise control. The fixed trunnion design provides excellent stability, reduced operating torque, and bubble-tight sealing under severe fluid pressures. Designed in strict accordance with API 6D standards, it is an ideal high-performance solution for petrochemical, water treatment, and municipal fluid transmission systems.

🏭 Engineering & Compliance Highlights:

  • Standard Compliance: Built and certified to API 6D, ASME B16.34, and DIN EN 1983.
  • Actuation: Premium manual gear operator with handwheel ensures effortless control of the massive 14″ bore.
  • Structural Advantage: Fixed ball design with bottom trunnion support ensures superior seal integrity and evenly distributes fluid load.
  • Material Quality: High-grade CF8 (ASTM A351) stainless steel for maximum industrial corrosion resistance.
