6 Operation
 The maximum permissible pressure drop in the inlet lines to the safety valves may not exceed the 3 %
pressure difference between the response pressure and superimposed back pressure on the safety
valve.
 Vibrations are to be avoided.
 Check the following points prior to start-up:
 All mounting and installation work are completed.
 Compare the material, pressure, temperature and installation position with the layout plan for the
pipework system.
 Dirt and residues have been removed from the pipeline and safety valve in order to prevent leaks.
6.1 Liftability (manual actuation for testing)
 Liftable safety valves are equipped with an appropriate device above the spring cap.
 Liftable safety valves can be made to open at ≥85 % of the set pressure without aids.
 Typical lifting cases are initial commissioning, after breaks in operation and functional testing; the pro-
cedure is as follows:
