Note
For temperature regulators with safety tem-
perature limiter (TR/STL), install the sensor of
the limiter near the control thermostat sensor.
Dynamic behavior of Type 2430 Control
Thermostat
The dynamics of the regulator are mainly de-
termined by the response of the sensor with
its characteristic time constant. Table 5-1
shows the dynamic behavior of the
Type 2430 Control Thermostat measured in
water.
Capillary tube
Carefully run the capillary tube without
bending or twisting it. Avoid locations with
considerable ambient temperature fluctua-
tions along the entire length of the tube.
Note
Do not damage or shorten the capillary
tube. Roll up any capillary tube that is not
used. The smallest permissible bending radi-
us is 50 mm.
Support and suspension
Note
The plant engineering company is responsi-
ble for selecting and implementing a suitable
support or suspension of the installed regula-
tor and the pipeline.
EB 3132-3 EN
Depending on the regulator version and
mounting position, the valve, actuator and
pipeline must be supported or suspended.
NOTICE
!
Do not attach supports directly to the regula-
tor.
Control line (to be provided on site)
Route the control line on site preferably using
a 6x1 mm (stainless) steel pipe.
The control line for tapping pressure from the
pipeline (for Type 2479/2430) must be in-
stalled upstream of the consumer. The pres-
sure tapping point must at least three times
the nominal size (DN) away from any pipe
fittings (e.g. restrictions, bends or branches),
that may cause turbulence in the flow. How
the lines are routed generally depends on
the installation site.
Î Preferably connect the control line to the
side of the main pipe (see Fig. 5-3).
Î Do not change the pipe diameter of the
main pipeline with an eccentric reducer.
