2.4 Life cycle
The valves are not subjected to constructive restrictions in their life cycle.
A leak test should be effected at least twice a year.
After each release (in case of fire or test release) the setting screw must be
calibrated with 10 to 11 Nm.
2.5 Handling
Before the valves will be installed on pressure gas cylinders, they have to be handled
and transported with care. Reason for this is to avoid damages of the lever group
and threads (inlet and outlet). A falling down of the valve, that would cause a
damage of the material or even an injury to persons, has to be prevented.
