Our trunnion mounted ball valves are engineered for easy and smooth operation at high line pressures, supported by carefully aligned bearings that ensure low torque operation. The ball is securely fixed in position but remains free to turn, providing reliable control. These valves are made with high-quality castings and feature a fire-safe design certified according to BS 6755, API 607, and API 6FA, meeting all applicable ASME standards. Our cast steel trunnion ball valves, available in Two Piece Split Body and Three Piece Bolted Body configurations, are designed and manufactured to the latest international standards, including API 6D, ASME B16.34, and BS 5351 or equivalents. They come with standard features such as Fire Safe, Anti-static, and Stem Blow-out Proof, making them ideal for a variety of industrial applications.
