Trunnion Mounted Ball Valves are engineered for smooth, low-torque operation even under high-pressure conditions. Equipped with precisely aligned bearings, these valves ensure effortless performance. The ball remains fixed in position but is free to rotate, allowing optimal sealing and flow control. Manufactured using high-quality castings, all valves feature fire-safe designs certified to BS 6755, API 607, and API 6FA standards, and fully comply with applicable ASME requirements. We offer both two-piece split body and three-piece bolted body designs. These valves are designed and manufactured to international standards such as API 6D, ASME B16.34, and BS 5351. Standard features include fire-safe construction, anti-static components, and blow-out-proof stems, ensuring safety, durability, and reliable performance in critical applications.
