Giacomini Manifold Thermal Actuator R473E

The best solution to enjoy ideal control of the room temperature by combining energy saving to top-notch comfort is the
installation of thermo-electric actuators on distribution manifolds, valves with thermostatic option or fan coil valves.
The normally closed R473E/R473HE thermo-electric actuators are totally noiseless and highly durable as they do not include
mechanisms subject to wear and tear. In addition, they close sufficiently slowly to prevent water-hammering.

The operation mechanism is made of wax bulbs controlled by low consumption electrical PTC (Positive Temperature Coefficient).

Suitable for replacing the following actuators:
