Trunnion Mounted Ball Valves are engineered for smooth, low-torque operation even under high line pressure, thanks to precision-aligned bearings and a robust trunnion-supported design. Unlike floating ball valves, the ball remains fixed but rotates freely, ensuring reliable performance with reduced wear and superior sealing.
All cast trunnion ball valves are fire-safe certified to BS 6755, API 607, and API 6FA standards, and comply with the latest ASME, API 6D, and BS 5351 specifications. These valves are available in both two-piece split body and three-piece bolted body constructions, offering flexibility for a wide range of industrial applications. Standard features include: Fire-safe construction, Anti-static design, Blowout-proof stem
