Installation
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 sufcient space
to remove the actuator and valve or to
perform service work on them.
Mounting position
To ensure that the valve can be drained and
cleaned properly, SAMSON recommends in-
stalling the valve with the actuator upright
and on top of the valve.
Î Contact SAMSON if the mounting posi-
tion is not as specied 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.
