Full Bore Top Entry Ball Valve, API 6D, WCB, 20 Inch, 600 LB

Key Specifications / Features

The Full Bore Top Entry Ball Valve features a trunnion-mounted design and is manufactured in accordance with API 6D standards. It has a carbon steel ASTM A216 WCB body, ensuring strength and reliability. With a size of 20 inches (DN500), a Class 600 LB pressure rating, and a PN100 pressure class, it is suitable for high-pressure applications. The valve also includes RF (Raised Face) ends.

Top Entry Trunnion Ball Valves offer an ideal solution for both offshore and onshore systems. Designed for easy operation and maintenance, these valves simplify in-line disassembly for trim inspections or internal repairs, even in space-restricted environments. They provide excellent corrosion resistance and superior sealing performance at both high and low pressures. Constructed from a single forged or cast piece, the valves feature two independent seats for bi-directional sealing and are manufactured according to customer specifications and international standards.
