Intended use
The gas pressure regulator VGBF serves to maintain
a constant outlet pressure p
a
despite changing gas
flow rates and inlet pressures p
e
in gas pipelines.
This function is only guaranteed when used within
the specified fields of application – see [Technical
data – p. 5].
Any other use is considered as non-compliant.

Installation
CAUTION
Please observe the following to ensure that the
gas pressure regulator is not damaged during the
installation:
Install the unit free of mechanical stress.
Sealing material, cuttings and other impurities must
not be allowed to get into the regulator housing.
The installation location must be dry. Do not install
the unit in the open air.
Installation in the vertical or horizontal position,
never upside down.
▷
▷
The outlet pressure p
a
is set at the factory with
the spring dome pointing vertically upwards. If
the VGBF is installed with the spring dome in the
horizontal position, check and adjust the outlet
