Installation
easily access the device from the work posi-
tion.
Pipeline routing
The inlet and outlet lengths (see Table 5-1)
vary depending on several variables and
process conditions and are intended as rec-
ommendations. Contact SAMSON if the
lengths are signicantly shorter than the rec-
ommended lengths.
To ensure that the valve functions properly,
proceed as follows:
Î Observe the inlet and outlet lengths (see
Table 5-1). Contact SAMSON if the
valve conditions or states of the medium
process deviate.
Î Install the valve free of stress and with the
least amount of vibrations as possible.
Read information under “Mounting posi-
tion” and “Support or suspension” in this
chapter.
Î Install the valve allowing sufcient space
to remove the actuator and valve or to
perform service work on them.
Mounting position
Generally, SAMSON recommends installing
the valve with the actuator upright and on
top of the valve.
In the following versions/applications, the
valve must be installed with the actuator on
top:
− Nominal sizes DN100 and larger
− Valves with insulating section or bellows
seal for low temperatures below –10°C
Î Contact SAMSON if the mounting posi-
tion is not as specied above.
Support or suspension
The plant engineering company is responsi-
ble for selecting and implementing a suitable
support or suspension of the installed control
valve and the pipeline.
Depending on the valve version and mount-
ing position, the valve, actuator and pipeline
must be supported or suspended.
Valves, which are not installed in the pipe-
line in the upright position with the actuator
on top, must be supported or suspended.
Valve accessories
Î During connection of valve accessories,
make sure that they are easily accessible
and can be operated safely from the
work position.
Vent plugs
Vent plugs are screwed into the exhaust air
ports of pneumatic and electropneumatic de-
vices. They ensure that any exhaust air that
forms can be vented to the atmosphere (to
avoid excess pressure in the device). Further-
more, the vent plugs allow air intake to pre-
vent a vacuum from forming in the device.
Î Locate the vent plug on the opposite side
to the work position of operating person-
nel.
5.2 Preparation for installation
Before installation, make sure the following
conditions are met:
− The valve is clean.
