ASTM A890 4A Trunnion Ball Valve, API 6D, 24 Inch, CL300, RF

Key Specifications / Features

The Duplex Steel Ball Valve Supplier in China offers high-performance trunnion-mounted ball valves that comply with API 6D standards. These valves feature a robust ASTM A890 4A body, providing excellent strength and corrosion resistance. Available in a large 24-inch (DN600) size, they are rated for a pressure class of 300 LB (PN50). The valves come with RF (Raised Face) flanged ends for secure and reliable connections, making them ideal for demanding industrial applications.

Trunnion-mounted ball valves ensure smooth and effortless operation even under high line pressures. Precision-aligned bearings reduce torque requirements, while the ball remains fixed in position yet rotates freely for optimal control. All cast trunnion ball valves from are crafted from high-quality castings and feature fire-safe designs certified to BS 6755, API 607, and API 6FA standards. They fully comply with all relevant ASME codes.
Our cast steel trunnion ball valves in two main configurations: two-piece split body and three-piece bolted body. These valves are engineered and produced to the latest international standards, including API 6D, ASME B16.34, and BS 5351 or their equivalents. Standard features include fire-safe construction, anti-static design, and blowout-proof stems to ensure safety and reliability.
