RTA(O)M Thermal actuator

Thermal actuator 100 or 125 N

RTA(O)M Thermal actuator for control valves

RTA(O)M are thermal actuators with position indication for control of valves in heating or cooling systems. The actuator can be used to control radiator circuits, solar heating systems, heating or cooling coils, floor heating, etc.
The actuator uses a PTC resistor-heated elastic element and a compression spring. When the supply voltage is switched on, the wax element is heated, moving the integrated piston. The force generated by the movement is transferred to the valve stem, opening and closing the valve.

Installation

The actuator connects to the valve using an adapter with a snap-on connection. The actuator can be mounted vertically or horizontally. Upside down mounting is also possible but might reduce the life of the actuator.
The actuator can be adjusted to almost any brand of valve by simply connecting the actuator to a snap-on adapter. The actuator uses a patented solution which offers 100 % protection against leaking valves, ensuring a long lifespan.

Main features:

100% protection against leaky valves
Noiseless and maintanance-free
Available in normally closed (NC) or normally open (NO) models
Modern and compact design
