Trunnion-mounted ball valves provide easy and smooth operation under high line pressure conditions. Precisely aligned bearings ensure low operating torque, while the ball is securely fixed in position yet 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. 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 designs. They are designed and manufactured in accordance with the latest international standards, including API 6D, ASME B16.34, BS 5351, or equivalent specifications. Standard features include fire-safe construction, anti-static design, and blowout-proof stems.
