Trunnion-Mounted Ball Valves provide smooth and reliable operation even under high line pressure. Precisely aligned bearings enable low-torque operation, while the trunnion-supported ball remains fixed yet free to rotate, ensuring stability and optimal sealing. All cast trunnion ball valves feature high-quality castings and a fire-safe design, certified according to BS 6755, API 607, and API 6FA, and comply with all relevant ASME standards. Cast steel trunnion ball valves are available in two-piece split body and three-piece bolted body configurations. They are designed and manufactured according to the latest international standards, including API 6D, ASME B16.34, BS 5351, or equivalent specifications. Standard features include fire-safe construction, anti-static design, and blowout-proof stem for enhanced safety, reliability, and durability.
