Installation
Support or suspension
Note
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.
Flanges
− The flanges of the cooling water valve as
well as the inlet and outlet flanges of the
steam conditioning valve must be de-
signed for the same pressure rating.
− To facilitate the separation of the steam
conditioning valve and cooling water
valve for repair and servicing work, a
flange must be used to connect the cool-
ing water valve to the steam conditioning
valve. If necessary, fit a blind flange.
Temperature sensor
Î Install a temperature sensor at least 10 m
downstream of the valve.
Note
The exact distance is determined at the valve
sizing stage based on the operating data.
Valve accessories
If excessive heat radiates from the steam
conditioning valve, only mount valve acces-
sories (e.g. positioners) on the inlet side of
the cooling water valve.
5-2
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
the 'Design and principle of operation'
section) have been installed or prepared
as necessary before installing the valve.
