1. Connect the external set point pressure
line at the G ¼ connection. Max. pres
-
sure p
c
= 8 bar.
2. Adjust the set point pressure p
c
to obtain
and keep the required pressure constant.
Monitor the downstream pressure at a pres
-
sure gauge (see Fig. 3 on page 10).
The valve closes when the output pressure p
2
exceeds the adjusted set point.
