Trunnion-Mounted Ball Valves provide easy and smooth operation under high line pressure conditions. Precisely aligned bearings ensure low operating torque, while the trunnion-supported ball remains fixed in position yet free to rotate, enhancing stability and sealing performance. All cast trunnion-mounted ball valves are produced using reliable, high-quality castings and feature a fire-safe design certified in accordance with BS 6755, API 607, and API 6FA. The valves meet all applicable 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 in compliance with 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 and reliability.
