ASTM A352 LCB Ball Valve, 3-Piece, API 6D, 56 IN, CL600, RF

Key Specifications / Features

The ASTM A352 LCB Ball Valve Factory specializes in producing robust trunnion-mounted ball valves with a 3-piece body design, adhering to API 6D standards. These valves are crafted from low-temperature carbon steel, ensuring performance in demanding conditions. Available in a large 56-inch size with a Class 600 LB rating, they feature RF flanged ends, making them suitable for high-pressure applications in various industries.

Our trunnion mounted ball valves are designed for reliable and smooth operation under high line pressures. Precision-aligned bearings ensure low torque performance, while the ball remains fixed yet free to rotate. All cast trunnion ball valves are manufactured using high-quality castings and incorporate a fire-safe design, certified to BS 6755, API 607, and API 6FA. These valves comply fully with applicable ASME standards.
Available in two-piece split body and three-piece bolted body designs, cast steel trunnion ball valves are built to meet the latest international standards, including API 6D, ASME B16.34, and BS 5351. Standard features include fire-safe construction, anti-static design, and blowout-proof stem for enhanced safety and performance.
