KOSEN Trunnion Mounted Ball Valves are designed for smooth operation under high line pressures. The carefully aligned bearings ensure low-torque operation. The ball is fixed in position but free to rotate. All KOSEN Cast Trunnion Ball Valves feature reliable, high-quality castings and are fire-safe certified according to BS 6755, API 607, and API 6FA, meeting all applicable ASME standards.
Our 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 latest international standards, including API 6D, ASME B16.34, BS 5351, and equivalent standards. They come with standard features such as Fire Safe, Anti-static, and Stem Blow-out Proof designs.
