Trunnion Mounted Ball Valves offer effortless and smooth operation even under high line pressure conditions. The valves are equipped with precisely aligned bearings that facilitate low torque operation. The ball is securely positioned yet remains free to rotate. All Cast Trunnion Ball Valves are crafted from high-quality castings and feature a fire-safe design certified in accordance with BS 6755, API 607, and API 6FA. They also meet all relevant ASME standards. Cast Steel Trunnion Ball Valves are available in two configurations: 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, and BS 5351, or their equivalents. Standard features include fire safety, anti-static properties, and stem blow-out prevention.
