Trunnion-mounted ball valves are designed to provide easy and smooth operation under high line pressure. Precisely aligned bearings help minimize operating torque, ensuring reliable and efficient performance. In this design, the ball is securely fixed in position while remaining free to rotate. All cast trunnion ball valves feature high-quality, reliable castings and a fire-safe design certified in accordance with BS 6755, API 607, and API 6FA, and comply with all applicable ASME standards. Cast steel trunnion-mounted ball valves are available in two-piece split body and three-piece bolted body constructions. These valves are designed and manufactured in compliance with the latest international standards, including API 6D, ASME B16.34, and BS 5351, or equivalent specifications. Standard features include fire-safe construction, anti-static design, and blowout-proof stems, ensuring safe and dependable operation in demanding service conditions.
