Reduced Bore Top Entry Ball Valve, API 6D, A216 WCB, 10*8 IN

Key Specifications / Features

This Reduced Bore Top Entry Ball Valve, compliant with API 6D standards, features a cast carbon steel ASTM A216 WCB body for excellent strength and durability. With a 10 x 8-inch (DN250 x DN200) size, it is rated for Class 1500 LB and PN250 pressure, making it suitable for high-pressure applications. The valve is equipped with RTJ flanged ends.

Top Entry Trunnion Ball Valves are the perfect solution for both offshore and onshore systems. These valves are designed with convenience of operation and maintenance in mind, simplifying in-line disassembly for trim inspection or internal repairs, even in restrictive spaces. They offer excellent corrosion resistance and superior sealing performance at both high and low pressures. Manufactured in a single forged or cast piece, these valves are configured with two independent seats for bi-directional sealing. They are produced in accordance with customer-specific requirements and international standards.
