Electrothermal normally closed servo motor

(VT.TE3043.0) Electrothermal two-position servo motor VT.TE3043 is purposed for automatic control of radiator or collector thermostatic valve of water heating (including water-heated floor) or cooling systems of buildings. The action of the motor is based on expansion of liquid (toluene) in the bellow, when the electric current flows through the built-in heating element on a signal from room thermostat or controller.

Technical characteristics: power-supply voltage – 24 or 230 V (50 Hz); cross-section of conductors (2 pc.) – 0.75 mm²; wire length – 1 m; connection dimension – 30 x 1.5 m. Normally closed. Connection of servo motor to the valve is performed using an adapter (included into the delivery set).

The servo motor works under control of thermostats VT.AC601, VT.AC602, VT.AC616I, VT.AC701, VT.AC709, VT.AC710.

This model of servo motor is assembled by a Chinese branch of Möhlenhoff factory from German components.
