Trunnion-Mounted Ball Valves offer effortless and smooth operation even under high line pressure. Precision-aligned bearings ensure low-torque operation. The ball is securely positioned yet able to rotate freely. All Cast Trunnion Ball Valves are made with reliable, high-quality castings and feature a fire-safe design certified to BS 6755, API 607, and API 6FA. They also meet all applicable ASME standards. Cast Steel Trunnion Ball Valves are available in Two-Piece Split Body and Three-Piece Bolted Body configurations. These valves are designed and manufactured in accordance with the latest international standards, including API 6D, ASME B16.34, and BS 5351 or their equivalents. They come with standard features such as fire safety, anti-static properties, and stem blow-out prevention.
