The pressure regulator plates can be set using the following
operator control elements:
– For the widths 18 ... 52 mm with the rotary knob
– Alternatively, with widths 18 mm and 26 mm with the
adjusting screw in the rotary knob.
Note
For the A-, B- and AB-pressure regulators type VABF-S4...
and VABF-S2... (identifier in the type code: R2, R3, R4), the
control pressure should not be under 2 bar. For regulator
pressure below 2 bar, use the reversible A-, B- or AB-pres-
sure regulators (identifier in the type code: R6, R7, R5)
see Tab. 1/9.
Setting the pressure regulator in size ISO2:
When setting the pressure regulator, if the rotary knob cannot
be operated because it is encapsulated by the adjacent
rotary knobs, the rotary knobs of the adjacent pressure
regulator can be dismounted briefly. This results in sufficient
space to operate the rotary knob.
For the standard pressure regulator, proceed as follows:
1. On the corresponding pressure regulators, forcefully pull
the rotary knob upward from the regulator head.
2. Set the control pressure on the corresponding pressure
regulator.
3. Place the rotary knob back onto the pressure regulating
valve.
4. Press the rotary knob down to the housing.
