Trunnion Mounted Ball Valves offer easy and smooth operation even at high line pressures. The valves are equipped with carefully aligned bearings that facilitate low-torque operation. The ball is securely positioned yet free to rotate. All Cast Trunnion Ball Valves 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 types: Two-Piece Split Body and Three-Piece Bolted Body. These valves are designed and manufactured to the most up-to-date international standards, including API 6D, ASME B16.34, BS 5351, or their equivalents. They come with standard features such as Fire Safe, Anti-Static, and Stem Blow-out Proof.
