Assembly
Do not attach supports directly to the valve
or actuator.
Do not install any instruments (e.g. tempera
-
ture regulators or shut-off valves) that restrict
the cross-section of the pipe between the
pressure tapping point and the regulator.

Mounting position
Î
Install the actuator housing with the set
point springs suspended downward in
horizontal pipelines (see section Fig. 6).
Î
Install a strainer upstream of the regula-
tor (see section 5.4.1).
−
For media with a tendency to conden-
sate, install the pipeline with a slight
downward slope on both sides so that
the condensate can drain properly. If the
pipeline upstream and downstream of
the regulator run vertically upwards, an
automatic water drainage is required.
Î
Make sure the direction of flow matches
the direction indicated by the arrow on
the body.
Î
Install the regulator free of stress.
Î
Make sure that the regulator remains
freely accessible after the plant has been
completed.
Damage due to freezing.
Protect the regulator from icing up when
controlling media that can freeze. Remove
the regulator from the pipeline when the
plant is shut down if the regulator is not
installed areas free from frost.
