    Abstract - (Show below) - (Hide below)

    ISO 4126-4:2013 specifies general requirements for pilot operated safety valves, 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.

    It is applicable to pilot operated safety valves having a valve flow diameter of 4 mm and above which are for use at set pressures of 0,1 bar gauge and above. No limitation is placed on temperature.

    ISO 4126-4:2013 is a product standard and it is not applicable to applications of pilot operated safety valves.
