Trunnion Mounted Ball Valves allow easy and smooth operation under high line pressure. Carefully aligned bearings ensure low-torque performance. The ball is fixed in position but free to rotate, allowing efficient flow control. All casted trunnion ball valves feature high-quality castings and a fire-safe design, certified according to BS 6755, API 607, and API 6FA. These valves comply with all applicable ASME standards.
Cast steel trunnion ball valves are available in two-piece split body and three-piece bolted body types. They are designed and manufactured in accordance with the latest international standards, including API 6D, ASME B16.34, and BS 5351 or their equivalents. Standard features include fire safety, anti-static construction, and a blow-out-proof stem.
