The 230 V thermoelectric valve drive is used to open
and shut valves in heating, ventilation and air
conditioning technology. It is controlled by a room
temperature control unit (230 V) with a two-step
output or pulse width modulation.
A large selection of valve adapters ensures that it
conforms perfectly to a range of valve bodies and
heating circuit distributors. The 230 V thermoelectric
valve drive therefore has universal applicability and is
suitable for a diverse range of systems.
De-energised - closed
The control mechanism of the thermoelectric valve
drive works with a PTC-heated expanding element and
a compression spring. The expanding element is
heated when the operating voltage is applied. After
the delay period has expired, the valve will open
uniformly. When the operating voltage is switched off,
the expanding element will cool down and, when the
idle time has expired, the valve will be closed
uniformly by the closing pressure of the compression
spring. The closing pressure of the compression
spring (90 N controlling torque) has been matched to
the closing pressure of commercially available valves
and holds the valve closed in its de-energised state.
First-open function
In the supplied state, the 230 V thermoelectric valve
drive is opened without current using the first-open
function. This makes it possible to operate the heating
during the shell construction phase, even if the
electrical wiring of the single room heating has not
been completed. When started up at a later stage, the
first-open function is automatically released when the
operating voltage is applied (for longer than 6 min), and
the 230 V thermoelectric valve drive is then ready to
function normally.
Functional display
The functional display of the thermoelectric valve drive
(all-round display) makes it possible to see the
operating status (valve "open", "closed" or in an
intermediate position) at a glance.
