11. Setting
11.1 Regulator setting

Setting of the outlet pressure

The regulator is set using the adjusting screw B.

1. Remove the protective cap A.

2. Turn the adjusting screw B using an open-ended 

wrench SW 24 mm.

3. Turning clockwise: the preload of the setpoint spring is 

increased and the outlet pressure p

ds 

 is increased (+).

4. Turning counter-clockwise: the setpoint spring is re

-

leased and the outlet pressure p

ds

 reduced (–).

5. After the setting: screw on the protective cap A again.
