Trunnion-mounted ball valves provide smooth and easy operation even under high line pressure. Precisely aligned bearings ensure low operating torque. The ball is securely fixed in position while remaining free to rotate. All cast trunnion 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, meeting 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 accordance 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 stem.
