标准摘要
[中文适用范围]： 本国际标准规定了与液压减压阀、顺序阀、卸荷阀、节流阀和止回阀安装表面有关的尺寸和其他数据，以确保互换性。 适用于代表当前实践的液压减压阀、顺序阀、卸荷阀、节流阀、止回阀的安装面；它们通常适用于工业设备。 [外文原描述]： ISO 5781:2016 specifies the dimensions and other data relating to surfaces on which hydraulic pressure-reducing valves, sequence valves, unloading valves, throttle valves and check valves are mounted in order to ensure interchangeability. It applies to mounting surfaces for hydraulic pressure-reducing valves, sequence valves, unloading valves, throttle valves and check valves, which represent current practice; they are generally applicable to industrial equipment.
