8.1.1 Pressure regulator with pressure outlet
Permissible inlet pressure range: .............. 1.1 to max. 30 MPa (11 to max. 300 bar) (depend-
ing on inlet connection)

*) at minimum inlet pressure (1.1 MPa) and nominal flow
By design the outlet pressure increases linearly as the inlet pressure decreases (approx.
150 kPa (1.5 bar) at 30 MPa falling to 1,1 MPa (300 bar falling to 11 bar)).
The actual outlet pressure is determined by the flow rate and the instantaneous inlet
pressure (see Section "Flow curves").
The flow is also dependent on the type of gas. Please consult the table below for the
nominal flow of gases other than air. Any downstream flow control unit must be suitable
for the gas used.

8.1.2 Pressure regulator flow outlet
Permissible inlet pressure range: ............. 1.1 to max. 20 MPa (11 to max. 200 bar)
(depending on inlet connection)
Configurable nominal gas volume flows and accuracy (gas temperature 20 ± 2 °C; 1013
hPa, free flow into the atmosphere)
Due to the design of the appliance, the gas volume flow varies in response to fluctuations
in the pressure of the gas supply and temperature fluctuations, as well as when the flow
resistance at the outlet changes, e.g. on account of downstream equipment.
8.1.2.1 Locking adjustable flow outlet
Flow setting range: ........... 0.1 – 30 l/min
(depending on the combination of orifices)
Accuracy when flow < 1.0 l/min: ..... -20 / +15% of the displayed value
Accuracy when flow 1 - 30 l/min: ... ±15% of the displayed value
