KOSEN Trunnion Mounted Ball Valves offer easy and smooth operation under high line pressure. Carefully aligned bearings facilitate low-torque operation. The ball is fixed in position but free to turn. All cast trunnion ball valves manufactured by us feature reliable, high-quality castings and a fire-safe design, certified according to BS 6755, API 607, and API 6FA. They meet all applicable ASME standards.

Our Cast Steel Trunnion Ball Valves are available in two types: Two-Piece Split Body and Three-Piece Bolted Body. They are designed and manufactured to the latest international standards, including API 6D, ASME B16.34, and BS 5351, or their equivalents. Standard features include fire safety, anti-static protection, and stem blow-out proof design.
