Trunnion Mounted Ball Valves are designed to provide smooth operation under high line pressures. Featuring carefully aligned bearings for low-torque operation, these valves offer a robust solution with minimal effort required to operate. The ball is fixed in position but free to rotate, ensuring efficient flow control. KOSEN's Casted Trunnion Ball Valves are crafted with high-quality castings and feature a fire-safe design, certified in accordance with BS 6755, API 607, and API 6FA. These valves meet all applicable ASME standards and are available in both two-piece split body and three-piece bolted body designs. Manufactured to the latest international standards, including API 6D, ASME B16.34, and BS 5351, these valves are equipped with standard fire-safe, anti-static, and blow-out proof stem features.
