During the tank filling, the blanketing regulator does not operate, and the excess inert gas is dumped into the
atmosphere by the pressure relief valve or by a double function, vacuum-breaker valve.
Without the tank product inflowing or discharging, the system remains hermetically sealed. If there are leaks in the
tank connections or welds, the regulator will operate to maintain the system pressure.

6 – INSTALLATION
The Regulator is supplied tested and calibrated by the factory.
The pressure settings, spring range and leak checking are carried out in a test bench according to the supply and
blanketing pressures specified by the client.
After being tested and calibrated, no further adjustment to the CELTIC N components is required, except for an
eventual fine adjustment of the setscrew.
