Installation
lengths are significantly shorter than the rec-
ommended lengths.
To ensure that the valve functions properly,
proceed as follows:
Î
Observe the recommended 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 ‘Legend’ in this section.
Î
Install the valve allowing sufficient space
to remove the actuator and valve or to
perform service and repair work on
them.
Mounting position
We recommend mounting the valve at an
angle between 15 and 25° to the horizontal
plane.
Î
Contact SAMSON if the mounting posi-
tion is not as specified 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.
For versions with side-mounted handwheel
which are installed at an angle of <45° to
the horizontal plane, the control valve 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.
− The valve and all valve accessories (in-
cluding piping) are not damaged.
− The valve data on the nameplate (type
designation, valve size, material, pres-
sure rating and temperature range)
match the plant conditions (size and
pressure rating of the pipeline, medium
temperature etc.). See the 'Markings on
the device' section for nameplate details.
− The requested or required additional
pipe fittings (see 'Additional fittings' in
