Trunnion-mounted ball valves are designed to provide smooth and reliable operation under high line pressure. Precisely aligned trunnion and stem bearings reduce operating torque, ensuring easy valve actuation. The ball is securely fixed in position while remaining free to rotate, delivering stable and consistent performance. All cast steel trunnion ball valves are produced using high-quality castings and feature 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 ball valves are available in two-piece split-body and three-piece bolted-body designs. They 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 a blowout-proof stem.
