Trunnion Mounted Ball Valves allow easy and smooth operation at high line pressure. Carefully aligned bearings assist in low-torque operation. The ball is fixed in position but free to turn. All Cast Trunnion Ball Valves 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. Cast Steel Trunnion Ball Valves manufactured by Vatac are available in Two-Piece Split Body and Three-Piece Bolted Body types. They are designed and manufactured to the most updated international standards: API 6D, ASME B16.34, BS 5351, or equivalents, with standard features including Fire Safe, Anti-static, and Stem Blow-out Proof.
