标准摘要
[中文适用范围]： 本国际标准规定了尺寸为 0203、05、0708 和 10 的四通组合叠加阀和四通方向控制阀在安装表面上的夹紧尺寸。 尺寸和尺寸符合 ISO 4401，以确保这些阀门的互换性并减少要使用的固定装置的数量。 它适用于代表当前实践的四通叠加阀和四通方向控制阀的夹紧尺寸。 它们通常适用于工业设备。 [外文原描述]： ISO 7790:2013 specifies clamping dimensions of four-port modular stack valves and four-port directional control valves, sizes 02, 03, 05, 07, 08, and 10, on mounting surfaces. The dimensions and sizes conform to ISO 4401 so as to ensure interchangeability of these valves and to reduce the number of fixing devices to be used. It applies to clamping dimensions of four-port modular stack valves and four-port directional control valves which represent current practice. They are generally applicable to industrial equipment.
