ATLAS thermal actuators open and close underfloor heating manifold valves in response to room thermostat commands, allowing zones to follow their heat demand. The electrothermal principle provides quiet actuation and links room control to the manifold circuits.
An M30 × 1.5 mm connection, 100 N thrust and 4 mm stroke provide specific data for matching manifold valves. Valve-pin geometry and closing dimensions must be checked as well as the thread; a matching connection size alone does not establish compatibility with every manifold.
230 V and 24 V supply options and normally closed or normally open models allow selection for the electrical control arrangement and required operating behaviour. IP54 protection and a manual opening feature for installation support fitting and commissioning in suitable environments. Supply and control type are matched to the ordered model.
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.
