Trunnion-mounted ball valves enable easy and smooth operation even at high line pressures. Carefully aligned bearings facilitate low-torque operation. The ball is securely positioned yet free to rotate. All cast trunnion ball valves are made from reliable, high-quality castings and feature a fire-safe design certified according to 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 B61.34, and BS 5351, or their equivalents. They come with standard features such as fire-safe, anti-static, and stem blow-out prevention.
