SAMSON's After-sales Service department
can provide more detailed storage instruc-
tions on request.
4.4 Preparation for installation
Proceed as follows:
Î
Check to ensure that the connection for
the safety temperature limiter at the valve
is clean.
Î
Check the safety temperature limiter for
damage.
Î
Check to make sure that the type desig-
nation, pressure rating and temperature
range of the safety temperature limiter
match the plant conditions (size and
pressure rating of the pipeline, medium
temperature etc.).
Î
Check any mounted thermometers to
make sure they function.
Tip
5 Mounting and start-up
Risk of overheating due to excessive ambient
temperatures or insufficient heat dissipation
when components are insulated.
Do not include the safety temperature limiter
in the insulation of the pipeline.
5.1 Assembling the safety tem-
perature limiter and valve
See Fig. 2.
The Type 2439 Safety Temperature Limiter is
always installed in combination with a valve
as a safety temperature regulator (STL). The
operating element with the spring mecha-
nism (STL) can be attached to the valve body
using the coupling nut (15) either before or
after the valve is installed in the pipeline.
The following points must be observed
during installation:
Î
Observe the permissible ambient tem-
perature range from 0 to 80 °C (0 to
60 °C when an signal transmitter is
used).
Î
Make sure that the regulator remains
freely accessible after the plant has been
completed.
Î
Install the valve in a horizontal pipeline
with the operating element connection
suspended downward (see Table 2).
