FCT Fully Welded Trunnion Mounted Ball Valve

FCT Fully Welded Trunnion Mounted Ball Valve

FCT Fully Welded Trunnion Mounted Ball Valve – Long-Term Reliability Without Maintenance

FCT fully welded trunnion mounted ball valves are built for the most demanding pipeline applications, including gas and oil transmission, underground installations, and subsea operations. The fully welded body eliminates external leakage paths and minimizes potential corrosion zones, making these valves ideal for long-term service with minimal maintenance.

With a trunnion-supported ball, low operating torque, and optional double block and bleed, these valves ensure high-integrity isolation and efficient in-line operation, even under extreme pressure and temperature conditions.
