Trunnion-mounted ball valves provide easy and smooth operation under high line pressure. Carefully aligned bearings ensure low operating torque. The ball is fixed in position while remaining free to rotate. All cast trunnion ball valves feature reliable, high-quality castings and a fire-safe design certified in accordance with BS 6755, API 607, and API 6FA, and meet all applicable ASME standards. Cast steel trunnion ball valves are available in two-piece split-body and three-piece bolted-body designs. The valves are designed and manufactured in accordance with the latest international standards, including API 6D, ASME B16.34, and BS 5351, or equivalent standards. Standard features include fire-safe construction, anti-static design, and a blowout-proof stem.
