5.1 Installing the valve into the
pipeline
5.1.1 Installation conditions
−
Choose a place of installation that allows
you to freely access the regulator even
after the entire plant has been complet-
ed.
−
The type and dimensions of the pipeline
and tank connections must suit the regu-
lator.
− Make sure the direction of flow matches
the direction indicated by the arrow on
the body.
−
Install the regulator free of stress and
with the least amount of vibrations as
possible. If necessary, support the pipe-
line near to the connecting flanges. Do
not attach supports directly to the valve
or actuator.
−
Protect the regulator from icing up when
controlling media that can freeze. Unless
the regulator is installed in locations
where no frost occurs, remove the regu-
lator from the pipeline when the plant is
shut down.
−
Observe the permissible ambient tem-
peratures (see section Table 1).
