Installation
5 Installation
The work described in this section is only to
be performed by personnel qualified for the
assignment accordingly.
5.1 Installation conditions
Work position
The work position for the regulator is the
front view onto all operating controls on the
regulator (including any additional fittings)
seen from the position of operating person-
nel.
Plant operators must ensure that, after instal-
lation of the device, the operating personnel
can perform all necessary work safely and
easily access the device from the work posi-
tion.
Pipeline routing
The inlet and outlet lengths vary depending
on several variables and process conditions
and are intended as recommendations. Con-
tact SAMSON if the lengths are significantly
shorter than the recommended lengths.
To ensure that the regulator functions proper-
ly, proceed as follows:
Î
Observe the inlet and outlet lengths (see
Table 5-1). Contact SAMSON if the reg-
ulator conditions or state of the medium
process deviate.
Î
Install the regulator allowing sufficient
space to remove the actuator and valve
or to perform service work on them.
Î
Install the regulator free of stress and
with the least amount of vibrations as
possible. Read Mounting position and
Support or suspension in this section.
Mounting position
To ensure that the regulator functions proper-
ly, proceed as follows:
Î
Standard mounting position: install the
actuator housing suspended downward
in horizontal pipelines (see sec -
tion Fig. 5-1).
Î
Make sure the direction of flow matches
the direction indicated by the arrow on
the body.
Î
Contact SAMSON if the mounting posi-
tion is not as specified above.
Damage due to freezing.
Protect the regulator from icing up when con -
trolling media that can freeze. Remove the
regulator from the pipeline when the plant is
shut down if the regulator is not installed ar
-
eas free from frost.
When an external control line is to be con-
nected ( special version ), observe the follow -
ing:
Î
Connect the high pressure of the plant to
the high-pressure connection (+) of the
actuator (bottom diaphragm chamber)
Î
Connect the low pressure of the plant to
the low-pressure connection (–) of the
actuator (top diaphragm chamber). See
Fig. 5-2.
