本标准规定了船用法兰连接金属阀门结构长度及其极限偏差。本标准适用于船舶管路系统中公称压力范围为PN 系列中的0.25 MPa～4.0 MPa、CLASS系列中的125磅～300磅压力级；法兰连接尺寸和密封面按GB/T 2501、ASME B16.5、ASME B16.47的金属阀门的设计和说明。本标准没包括的其他公称压力或法兰连接尺寸金属阀门的结构长度可参照相近压力级执行。
Scope
This standard specifies the structural length and limit deviation of marine flanged metal valves. This standard applies to the nominal pressure range of 0.25MPa~4.0MPa in PN series and 125lb~300lb in CLASS series in the ship piping system; the flange connection size and sealing surface are in accordance with GB/T 2501, ASME B16 .5. ASME B16.47 metal valve design and specification. The structural length of metal valves with other nominal pressures or flange connection sizes not included in this standard can be implemented with reference to similar pressure levels.
