Thermal Actuator
Application
Ordering
The thermal actuator is a small actuator for elec trical
on/off controls and PWM to activate several types
of valves and floor heating manifolds.
The actuator is equipped with a visual position
indicator to show the open or closed position of
the valve.
The product range covers actuators for 24 V (SELV)
or 230 V supply in both normally closed (NC) or
normally open (NO) versions (valve positions with
no supply voltage to the actuator).
The actuator can be connected to valves with
Heimeier/MNG/Oventrop M30×1,5 connection.
Other valves must be verified individually to ensure
correct valve closing measurement and valve top
geometry.
Actuator Connection type Supply voltage Function Code no.

If the actuator should be a 24 V or 230 V and normally open (NO) or normally closed (NC) depends
mainly on the application, control strategy and the controller connected to the actuator.
