This part of this European Standard specifies general requirements for pilot operated safety valves, other than
those covered in Part 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.
It 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.
