Thermal actuators are electro-thermal drive elements used in underfloor heating systems that open and close the valves on the manifold in response to signals from room thermostats. Compatible with all heating manifolds thanks to their standard M30x1.5mm connection size, these actuators ensure safe operation with a 230V AC supply voltage and IP54 protection rating. With their quiet and energy-efficient design, they enable localised temperature control.
