Trunnion Mounted Ball Valves provide smooth and effortless operation even under high line pressure conditions. Precision-aligned bearings enable low torque actuation, ensuring reliable performance. The ball is securely fixed in position while allowing free rotation. All cast trunnion ball valves are manufactured with high-quality castings and feature a fire-safe design certified to BS 6755, API 607, and API 6FA standards. These valves fully comply with applicable ASME codes. Our fixed ball valve are available in two main configurations: Two-Piece Split Body and Three-Piece Bolted Body. Our cast steel trunnion ball valves meet the latest international standards including API 6D, ASME B16.34, and BS 5351 or their equivalents. Standard features include fire safety, anti-static protection, and stem blowout-proof design for enhanced operational safety.
