EMOtec - Electrothermal actuator for on / off control in surface heating systems, open currentless 24V 1829-00.500

The electrothermal actuator EMOtec is a two-position actuator cooperating with a temperature controller that sends a two-point signal, eg P room thermostat or System Radiocontrol-F for underfloor heating by IMI Heimeier.
The (normally closed) NC version of the actuator has a position indicator located centrally on the top of the actuator (valve closed / valve open).
230 V versions (with built-in 2.5 kV overvoltage fuse) and 24 V versions are available in (normally closed) NC or (normally open) NO versions.
EMOtec has an electrically heated expansion unit that is secured against overtravel.
During closing, the actuating force is matched to the soft-seated valve plugs. The actuator is maintenance-free and does not generate noise. Depending on the version, EMOtec is
