Trunnion Mounted Ball Valves are engineered for smooth, low-torque operation, even at high line pressures. The design incorporates precisely aligned bearings and a fixed-position ball that rotates freely, ensuring ease of operation under demanding conditions. These valves are manufactured using high-quality castings and conform to fire-safe standards certified by BS 6755, API 607, and API 6FA. All designs comply with ASME standards and international specifications including API 6D, ASME B16.34, and BS 5351. Available in two-piece split body and three-piece bolted body constructions, our trunnion ball valves are known for reliability, safety, and superior sealing performance.
