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.
