Trunnion Mounted Ball Valves offer easy and smooth operation at high line pressures, thanks to 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 manufactured 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. Available in Two Piece Split Body and Three Piece Bolted Body configurations, they are designed and manufactured to the latest international standards, including API 6D, ASME B16.34, and BS 5351 or equivalents. Standard features include fire safety, anti-static properties, and stem blow-out proof design, making them suitable for a wide range of industrial applications.
