Operation
Pressure testing the plant
All plant components must be designed for
the test pressure. Remove the regulator from
the pipeline, if necessary.
Risk of damage to the actuator diaphragm
due to impermissible excess pressure.
The pressure at the actuator must not exceed
the nominal valve pressure by 1.5 times and
the maximum permissible actuator pressure
on testing the pressure of the plant when the
regulator is already installed. If necessary,
detach the control line and seal the openings
with end plugs.
Rinsing the plant
After filling the plant, first completely open
the consumer. Rinse out the pipeline at full
flow rate for several minutes. Check the in
-
stalled strainer (e.g. by measuring the pres-
sure drop). Clean the strainer, if necessary.

Adjusting the set points
Turning the set point adjuster (6)
−
Turn clockwise
:
Tension the springs to increase the set point.
−
Turn counterclockwise
:
Relieve the spring tension to reduce the set
point.
How to proceed:
Î
Adjust the downstream pressure (p
2
) by
turning the set point adjuster (6) to load
the set point springs (7).
Î
Turn clockwise
:
Tension the springs to increase the set
point.
Turn counterclockwise
:
Relieve the spring tension to reduce the
set point.
Monitor the set point pressure to be adjusted
at the pressure gauge (see Fig. 6) installed
on the downstream pressure side.
