Installation example
− 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.
