Trunnion-mounted ball valves allow easy and smooth operation even under high line pressure. Precisely aligned bearings ensure low operating torque, while the ball remains fixed in position but free to rotate. All cast trunnion ball valves feature reliable, high-quality castings and fire-safe designs certified to BS 6755, API 607, and API 6FA. They meet all applicable ASME standards. Cast steel trunnion ball valves produced by Vatac are available in two-piece split-body and three-piece bolted-body configurations. They are designed and manufactured in accordance with the latest international standards, including API 6D, ASME B16.34, BS 5351, or equivalent specifications. Standard features include fire-safe construction, anti-static design, and a blowout-proof stem.
