Mounting and start-up
Do not put the safety temperature regulators
(STL) into operation before mounting the
valve and control thermostat.
Risk of damage to the valve or safety tem -
perature limiter due to excessively high or
low tightening torques.
The connection between valve and safety
temperature limiter must be tightened with a
certain tightening torque. Excessively tight -
ened torques lead to parts wearing out
quicker. Parts that are too loose may cause
leakage.
Observe the specified tightening torques.

5.2 Additional fittings
Strainer
A strainer installed upstream in the flow pipe
holds back any dirt or other foreign particles
carried along by the medium. For example,
the SAMSON Type 1 NI Strainer is suitable
(
u
T 1010).
The following points must be observed
during installation of the strainer:
−
Do not use the strainer to permanently
filter the process medium.
− Install the strainer upstream of the regu-
lator.
−
Allow sufficient space to remove the filter.
− Observe the flow direction.
−
In horizontal pipelines with gases or liq -
uids, the filter element faces downward.
The filter element faces sideways in ap
-
plications with steam.
− Install strainers in vertical pipelines with
the medium flowing upward with the
cover facing upward.
Shut-off valve
Install a hand-operated shut-off valve both
upstream of the strainer and downstream of
the regulator. This allows the plant to be shut
down for cleaning and maintenance, and
when the plant is not used for longer periods
of time.
Thermometer
Install a thermometer both upstream and
downstream of the regulator to monitor the
temperatures prevailing in the plant.
