TEMPTROL
4.2 Operating principles
The temperature regulator TEMPTROL® is a self acting proportional controller for
temperature of fluid, gas and vapour media of Fluid Group I pursuant to Pressure
Equipment Directive 97/23/EC. No auxiliary energy is needed.
The temperature regulator is a combination of controller and valve and is working acc. to
the principle liquid expansion by changing temperatures.
- Thermal closing valves reduce the flow with rising sensor temperature (heating
application).
- Thermal opening valves raise the flow with rising sensor temperature (cooling
application).
- Thermal mixing valves mix 2 flows (inlet A and inlet B to outlet AB).
- Thermal diverting valves divert one flow into 2 flows (AB to A and B).
Mixing/diverting valves open inlet A and closes inlet B with rising temperature.
Valves are available in several materials for specific media e.g. heating water, steam,
thermal oil, coolant water (other media available on request).
- Thermal detectors acc. to DIN EN 14597 can only be adjusted to the intended value with
tools.

5.0 Installation
5.1 General notes on installation
The following items should be taken into account besides the general principles governing
installation work:
Refer to data sheet for necessary resp. relevant data for correct installation;
e.g. dimensions, connections, max. operating limits, etc.
ATTENTION !
- Pressureless pipe system.
- Medium must be cool.
- Plant must be drained.
- Purge piping systems in case of caustic, inflammable, aggressive or toxic
media.
- Remove flange covers if present.
- The interior of valve and pipeline must be free from foreign particles.
- Note installation position with reference to flow, see mark on valve.
- Steam line systems should be designed to prevent water accumulation.
®
- Lay pipelines so that damaging transverse, bending and torsional forces are
avoided.
- Protect valves from dirt during construction work.
- Connection flanges must mate exactly.
- Connecting bolts for pipe flanges should be mounted preferably from the
counter flange side (hexagon nuts from the valve side).
At DN15-32: If valves should be mounted directly to valves, the upper flange
connecting bolts should be preferably executed with studs and hexagon nuts on
both sides.
- Valve mountings such as actuator, capillary tube, bonnets, temperature sensors
must not be exposed to external forces, e.g. they are not designed for use as
climbing aids, or as connecting points for lifting gear.
- Suitable materials handling and lifting equipment should be used.
Refer to data sheet for weights.
- If a temperature sensor is placed in a vessel with flammable or explosive media,
a sensor pocket have be provided.
- The actuator seals the valve interior only metallic;
not extra gasket is allowed!
- No sharp bending or unscrewing of capillary tubes is allowed; passes control
medium on hot surfaces it may ignite. Combustion danger!
- Planners / construction companies or operators are responsible for positioning and
installing products.
- The valves are designed for application, not influenced from weather.
- For application outside or in adverse environments like corrosion-promoting conditions
(sea water, chemical vapours, etc.), special constructions or protective measures are
recommended.
- Valve and controller/detector are delivered separately.
- Before installing the temperature regulator, rinse and clean the system otherwise the
seat / disc will be damaged and the control hole will be blocked.
- Centre packings between the flanges.

Operating and installation instructions
TEMPTROL
- Flow direction:
- Thermal closing valves:
The flow direction must correspond with the arrow on the valve body.
- Thermal opening valves (Inlet B closed):
Flow direction for thermal openting valves is preferably from A to B.
Inlet B must be closed with a blind flange.
(Flow direction from AB to A is possible, but not recommended, because oncoming
flow goes contrary the usual flow direction onto the plug.
®
- Thermal mixing/diverting valves:
When installing 3-way valves, it is important to distinguish between
mixing and diverting of flow.
- Mixing
The flow media inlets are A and B (the warmer medium should
enter inlet B).
- Diverting
The medium enters through inlet AB and exits out of outlets A and B.
In order to assure proper regulation, the pressures of both partial
flows (inflow for mixing or outflow for diverting) must be of equal
magnitude.
Please note, that with rising sensor temperature, inlet B (mixing) or
outlet B (diverting) are throttled.
The flow direction must correspond with the arrow on the valve
body.

5.2 Requirements at the place of installation
The place of installation should be easily accessible and provide ample space for
maintenance and removing the actuator and extracting the temperature sensor out of the
piping or tank. Install a stop valve upstream and downstream of the temperature regulator
to enable repair and maintenance work, without emptying the system. Also a strainer
should exist in front of the control valve (refer to point 5.5), to exclude wear between seat
and disc.
Insert thermometer to control the medium temperature. The piping diameters before and
behind the valve must ensure, that the allowed flow velocities are not exceeded.
- When insulating, the bonnet, actuator, capillary tube and temperature sensor must stay
free.
- The capillary tube of the temperature regulator must be installed in such a way that no
large temperature alterations and vibrations occur. The max. distance between the tube
holders is 250 mm. The min. bending radius is 50 mm. The connecting pipe is part of a
hydraulic system. It must not be disconnected or damaged.
- Temperature sensors (pos. 50.1) can be installed in systems with sensor pockets. The
sensor pocket enables easy installation, when a change is necessary the system must not
be emptied. Note the longer time constant!
- Installation with actuator hanging.

Operating and installation instructions
TEMPTROL
5.2.1 Thermo controller with 2 temperature sensors
- The first temperature controller (pos. 50.1a) (a bar sensor for liquids or a spiral sensor for
air) measures the external temperature (regulating variable).
- The second temperature controller (pos. 50.1b) (a bar sensor) measures the external
temperature (command variable). It should be mounted outside wall - north side away
form the sun, 2m above ground and protected from wind.
- The influence of the external temperature on the controlled temperature is possible due to
the difference in volume between the first sensor (regulating variable) and the second
sensor (command variable).
- The set point indicator has a trend scale with a middle mark (refer to setting diagrams in
the data sheet).
5.2.2 Selection of temperature sensor- Location
- The temperature sensor (pos. 50.1) must be completely immersed.
Care should be taken to assure adequate circulation.
- At low flow rates, we recommend installing the temperature sensor (pos. 50.1) horizontally
(for example in boilers at 2/3 height).
- The control thermometer should be installed near the location from temperature sensor.
- In pipelines, a threaded coupler must be welded into the pipe and the temperature sensor
mounted against the flow direction.
- When installing the temperature sensor (pos. 50.1) directly, be sure the connection is free
of leaks (gasket is included).
- Room temperature sensors should not be exposed to interference such as drafts, sunlight
and other sources of heat.

- The manual control device is installed between the valve (pos. 11) and the actuator
(pos. 50.16) of the thermal control valve (Fig. 5).
- Note, that here also the sealing is only metallic, no extra gasket!
- The connecting nut (pos. 60.14) is fastened with about 100 Nm to the valve (pos. 11), the
actuator (pos. 50.16) with about 50 Nm to the manual control device.
In the following, a setting example is shown for a closing valve:
- Turn the adjusting ring (pos. 60.5) clockwise till the valve (pos. 11) is closed (mechanical
endpoint). The upper securing ring (pos. 60.3) is put in line with the notch of the pin
(pos. 60.11).
- Now turn the adjusting ring (pos. 60.5) anti-clockwise, till the valve (pos. 11) is full open
(max. flow). The bottom securing ring (pos. 60.3) is put in line with the notch of the
indicator pin (pos. 60.11). In the system you can then see the lift over the open and closed
position between the securing rings (pos. 60.3).
- Note, that when working the adjusting ring (pos. 60.5) must be in the opening position of
the valve; closed valve can’t be opened through the thermal controller!

ATTENTION !
Operating and installation instructions
TEMPTROL
®
-
Install a strainer before the temperature regulator with the sieve sideways (with
the medium steam) to avoid the collection of condensate.
The strainer must be cleaned from time to time.
6.0 Putting the valve into operation
ATTENTION !
- Before putting the valve into operation, check material, pressure, temperature
and direction of flow.
- Putting into operation only through expert personnel.
- Regional safety instructions must be adhered to.
- Residues in piping and valves (dirt, weld beads, etc.) inevitably lead to leakage.
- Touching the valve when it is operating at high (> 50 °C) or low (< 0 °C) media
temperatures can cause injury.
Affix warning notice or protective insulation as appropriate!
Before putting a new plant into operation or restarting a plant after repairs or
modification, always make sure that:
- All works has been completed!
- The valve is in the correct position for its function.
- Safety devices have been attached.
- To avoid a to higher temperature on the sensor, firstly adjust to the max. range
of the setting range.
The operation is then as follows:
- After installation, valve and piping must be filled over the return line. If this is not possible,
slowly open (half open) the stop valve before the control valve, and carefully without
pressure surges, fill the piping. Then slowly fully open the stop valve.
- Any leakage tests may be conducted only when the valve is not closed.
Otherwise, internal valve components could be damaged.

Body screw
- The temperature setting is done through turning the setting ring (pos. 50.13). The body
(pos. 50.5) must be held fast; it is not allowed to turn.
- Setting of higher ranges is allowed without any restrictions.
- Setting for lower ranges when installed, is only allowed in small steps smaller 30 K.
Between the steps, the temperature regulation (system dependent about 15 min.) must be
waited for.
- When alterations larger than 30 K are done, the excess temperature indicator can
respond.
This can be seen when the setting ring (pos. 50.13) has moved upwards from the body
(Fig. 7) (pos. 50.5). In this case, the temperature regulation must be waited for, before
further alterations are done. Excess responses from the indicator shortens the lifetime
from the thermal controller!
Fig. 6: Setting range
Fig. 7: Excess temperature indicator
- After the temperature regulation in the system has been fulfilled, the actual temperature
can be seen on the control manometer.
- If both values which have been set are reached, then the procedure is ended.
- If the values are not correct, then a correction must be done on the set point indicator. The
set point must be altered to the actual value (see point 6.2).

Body screw
Fig. 8: Setting correction
- Loosen the body screw (M4).
- The correction is done through turning the body (pos. 50.5) till the setting is equal to the
actual temperature (actual value on control manometer). The setting ring (pos. 50.13)
(tools with detector) must be held; it is not allowed to turn.
- Set to the needed value.
(Turn the setting ring (pos. 50.13) (tools with detector) - Hold body (pos. 50.5)).
- After the temperature regulation in the system had been fulfilled, read again the actual
temperature.
- If both values are the same, the procedure is ended.
- If the value has not been successfully reached, repeat the setting correction.
- When the correction is done, turn the body (pos. 50.5) so far, that the setting range can be
seen, then fasten the screw.
7.0 Care and maintenance
Maintenance and maintenance-intervals have to be defined by the operator according to
the requirements.
