GB/T 584-2026Marine cast steel flanged stop valves (English PDF)

GB/T 584-2026 is the English-translated version of 船用法兰铸钢截止阀.

Marine cast steel flanged stop valves are covered by this standard. Stop valves of this type are used in shipboard piping to start, stop, or regulate flow, and a product standard sets common expectations for suppliers and buyers in shipbuilding.

Valve manufacturers, shipyards, ship designers, classification and inspection bodies, and marine equipment buyers are the principal users. It is a recommended national standard (GB/T), so it is voluntary unless a contract or class rule invokes it. This 2026 edition replaces GB/T 584-2008, and project documents that cite the earlier version should be reviewed. The standard was issued on 28 September 2026 and takes effect on 1 January 2027. It is a companion to other marine valve standards in the same batch, including the one for cast iron flanged stop check valves, which concerns a different valve type made from a different material.
