标准范围

ISO 4126-4:2003规定了先导式安全阀的一般要求，而不是ISO 4126-1中涵盖的要求，无论其设计用于何种流体。在所有情况下，操作都是由待保护系统中的流体执行的。ISO 4126-4:2003适用于阀流直径为6 mm及以上的先导式安全阀，用于0.1 bar及以上的设定压力。温度没有限制。这是一个产品标准，与先导式安全阀的应用无关。

ISO 4126-4:2003 specifies general requirements for pilot operated safety valves, other than those covered in ISO 4126-1, irrespective of the fluid for which they are designed. In all cases, the operation is carried out by the fluid in the system to be protected.ISO 4126-4:2003 is applicable to pilot operated safety valves having a valve flow diameter of 6 mm and above which are for use at set pressures of 0,1 bar gauge and above. No limitation is placed on temperature.This is a product standard and it is not concerned with applications for pilot operated safety valves.
