Flow and temperature controller with / without integrated
control valve (PN 25)

AVQT - flow and temperature controller
AVQMT - flow and temperature controller with integrated pressure independent control valve

Description

AVQMT

AVQT

AVQT is a self-acting flow and temperature
controller primarily for use in district heating
systems. The controller closes on rising
temperature or when set max. flow is reached.

AVQMT is a self-acting flow and temperature
controller with integrated control valve primarily
for use in district heating systems. The controller
closes on rising temperature or when set max.
flow is reached.

AVQT controller can be combined with AVT or
STM thermostatic actuators.

AVQMT controller can be combined with Danfoss
electrical actuators AMV(E) (and controlled by
ECL electronic controllers) and with AVT or STM
thermostatic actuators.

The controllers AVQT and AVQMT have a control
valve with adjustable flow restrictor, connection
neck for thermostat, connection neck for
electrical actuator (AVQMT only), and a pressure
actuator with one control diaphragm.

AVQMT controllers combined with AMV(E) 13,
AMV(E) 23(SL) or AMV(E) 33 electrical actuators
are type-tested acc. to EN 14597.

AVQT and AVQMT controllers combined with AVT
or STM thermostatic actuators are type-tested
acc. to EN 14597.

Controllers combined with STM thermostatic
actuators protect systems against exceeding
temperatures.

- Heating systems acc. to EN 12828 (DIN 4751)
and EN 12953-6 (DIN 4752)

Installation positions

Flow and temperature controller with / without
integrated control valve (with AVT or STM)

Up to medium temperature of 100 °C the
controllers can be installed in any position.

For higher temperatures the controllers have
to be installed in horizontal pipes only, with a
pressure and temperature actuator oriented
downwards.

Media temperature 100 °C Media temperature 130 °C Media temperature 150 °C

Electrical actuator

Note!

Installation positions for electrical actuators AMV(E) have
to be observed as well. Please see relevant Data sheet.

Temperature sensor

The place of installation must be chosen in a way
that the temperature of the medium is directly
taken without any delay. Avoid overheating of
temperature sensor. The temperature sensor
must be immersed into the medium in its full length.

Data sheet AVQ(M)T (PN 25)

Function

Flow and temperature controller with / without
integrated control valve (AVQT, AVQMT)

Flow volume causes pressure drop across

the adjustable flow restrictor. Resulting
pressures are being transferred through the
impulse tubes and/or control drain in the
actuator stem to the actuator chambers and
act on control diaphragm for flow control.
The flow restrictor diff. pressure is controlled
and limited by means of built-in spring for
flow control. Control valve closes on rising
differential pressure and opens on falling
differential pressure to control max flow.

Additionally for AVQMT:

Additionally the electrical actuator will

operate from zero to set max. flow according
to the load.

Safety Temperature Monitor (STM)

- Function
The safety temperature monitor is

proportional temperature controller which
protects the system against exceeding
temperatures. The valve cone is soft sealed
and pressure relieved.

In case the temperature at the temperature

sensor exceeds the adjusted set point, safety
temperature monitor interrupts energy
supply by closing the valve. As soon as the
temperature at the temperature sensor drops,
the valve opens automatically.

Handle for limit setting can be sealed.

- Extended safety function

If there is a leakage in the area of the

temperature sensor, the capillary tube, or the
thermostat, the valve closes by a safety spring
in the safety thermostat. In this case safety
temperature monitor (actuator) must be
replaced.

- Physical Function Principle

The safety temperature monitor operates

in accordance with the liquid expansion
principle. The temperature sensor, the
capillary tube and the bellows are filled with
liquid. As the temperature at the temperature
sensor rises, the liquid expands, the
thermostat stem moves out and closes the
valve.

Temperature Controller (AVT)

- Function

By increasing of medium temperature valve

cone moves towards the seat (valve closes), by
decreasing of medium temperature control
valve moves away from the seat (valve opens).

Handle for temperature setting can be sealed.

- Physical Function Principle

Medium temperature changes cause pressure

changes in temperature sensor. Resulting
pressure is being transferred through the
capillary tube to the bellows. Bellows moves
thermostat stem and opens or closes the
valve.

Settings Temperature setting (AVT)

Max flow limiting

Max flow limiting is being done by the
adjustment of the flow restrictor position. The
adjustment can be performed on the basis
of flow adjustment diagram (see relevant
instructions) and/or by the means of heat meter.

Temperature setting is being done by the
adjustment of the setting spring for temperature
control. The adjustment can be done by means
of handle for temperature setting and/or
temperature indicators.

Limit setting (STM)

Limit setting is being done by the adjustment of
the setting spring for temperature control. The
adjustment can be done by means of handle for
limit setting and/or temperature indicators.
