Installation
5 Installation
The work described in this section is only to
be performed by personnel appropriately
qualified to carry out such tasks.
Valve and control thermostat can be assem-
bled before or after the valve has been in-
stalled in the pipeline. We recommend first
installing the valve without the control ther-
mostat into the pipeline.
5.1 Installation conditions
Work position
The work position for the control thermostat
is the front view onto the operating controls
on the regulator (including any additional fit-
tings) seen from the position of operating
personnel.
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
Î
Observe the recommended inlet and
outlet lengths (see the mounting and
operating instructions of the
corresponding regulator as listed under
'Referenced documentation' in the
'Safety instructions and measures'
section).
Î
Install the regulator and control thermo-
stat free of stress and with the least
amount of vibrations as possible. Read
information under ‘Mounting position’,
‘Temperature sensor (adsorption princi-
ple) for Type 2430’, ‘Temperature sensor
(vapor pressure principle) for Type 2430-
3’ and ‘Installation with thermowell’.
Î
Install the regulator allowing sufficient
space to remove the control thermostat
and valve or to perform service work on
them.
Mounting orientation
For gases and liquids above
80 °C/175 °F and steam
Mounting orientation
For gases and liquids at
medium temperature up to
80 °C/175 °F
Fig. 5-1: Mounting position
Mounting position
To ensure that the control thermostat and
regulator function properly, proceed as fol-
lows:
Î
The control thermostat can be mounted in
any position on the valve when the medi-
um temperature is up to 80 °C/175 °F.
Î
At medium temperatures above
80 °C/175 °F and with steam, install the
valve with the control thermostat sus-
pended downward in horizontal pipe-
lines (see Fig. 5-1).
