Installation; Installation Conditions - Samson 42-36 E Mounting And Operating Instructions

5 Installation

The work described in this section is only to
be performed by personnel appropriately
qualified to carry out such tasks.
Valve and electric actuator can be assem-
bled before or after the valve has been in-
stalled in the pipeline. We recommend first
installing the valve without the electric actua-
tor into the pipeline.

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.
EB 3018 EN
Î Install the regulator free of stress and
with the least amount of vibrations as
possible. Read information under
'Mounting position' and 'Support or sus-
pension' in this section.
Î Install the regulator allowing sufficient
space to remove the valve, actuator and
electric actuator or to perform service
work on them.
Mounting position
To ensure that the regulator functions proper-
ly, proceed as follows:
Î Install the actuator housing suspended
downward in horizontal pipelines (see
Fig. 5-1).
Î The electric actuator must be mounted
above the valve body.
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.
NOTICE
!
Possible malfunction and damage due to
adverse weather conditions (temperature,
humidity).
− Do not install the regulator outdoors or in
rooms prone to frost.
− Protect the regulator against frost if it is
used to control freezing media.
− Either heat the regulator or remove it from
the plant and completely drain the residual
medium.
