Trunnion-mounted ball valves ensure easy and smooth operation under high line pressure conditions. The precisely aligned bearings enable low-torque operation. The ball is securely positioned yet remains free to rotate. All cast trunnion ball valves produced by us are made with reliable, high-quality castings and feature a fire-safe design certified in accordance with BS 6755, API 607, and API 6FA. They meet all applicable ASME standards. Cast steel trunnion ball valves are available in two-piece split body and three-piece bolted body configurations. These valves are designed and manufactured to the latest international standards, including API 6D, ASME B16.34, and BS 5351, or their equivalents. They come with standard features such as fire-safe, anti-static, and stem blow-out prevention.
