Trunnion Ball Valve - Flanged Class 600

The Trunnion Ball Valve – Flanged Class 600 (BIAV-TBVFV-430) is designed for high-pressure, high-temperature pipeline applications. Its trunnion-mounted ball design ensures reduced operating torque and stable sealing under ANSI Class 600 ratings, providing secure isolation in oil, gas, and petrochemical industries.

Engineered with fire-safe, anti-static, and blowout-proof features, the Trunnion Ball Valve (BIAV-TBVFV-430) ensures compliance with API and ASME standards. Available with gear, pneumatic, or electric actuation, it delivers reliability, safety, and long-lasting performance in demanding industrial operations.

Selection checklist

  • Confirm system operating pressure & temperature against Class 600 rating (use flange pressure-temperature charts).

  • Choose material of construction for H₂S, sour service, or high-temp.

  • Is DBB (double block and bleed) required? If yes, specify.

Maintenance & commissioning

  • Hydrostatic test per API 6D or ASME B16.34 as required.

  • Torque verification on flange bolts to ensure seat sealing.

  • For optimal productivity, the BIAV-TBVFV-430 Trunnion Ball Valve requires periodic seat inspection; lubricate/bleed packing per manufacturer.
