Our trunnion mounted ball valves are designed for reliable and smooth operation under high line pressures. Precision-aligned bearings ensure low torque performance, while the ball remains fixed yet free to rotate. All cast trunnion ball valves are manufactured using high-quality castings and incorporate a fire-safe design, certified to BS 6755, API 607, and API 6FA. These valves comply fully with applicable ASME standards.
Available in two-piece split body and three-piece bolted body designs, cast steel trunnion ball valves are built to meet the latest international standards, including API 6D, ASME B16.34, and BS 5351. Standard features include fire-safe construction, anti-static design, and blowout-proof stem for enhanced safety and performance.
