Motorized Linear Actuator   

 

 

    baelz 373-E07

4.3  Principle of operation

Motorized linear actuators to operate control valves for flow regulation applications in control 

and process technology. The self-locking threaded spindle/spindle nut is driven by an electric 

motor via a gearbox. This converts the rotary movement into a linear movement. Load-

dependent limit switches dictate the end positions

4.3.1  Manual adjustment

Manual adjustment may only be carried out when the motor is not in motion. To adjust, press 

and hold the yellow release button and turn the manual adjuster until the desired position is 

reached. As soon as the yellow release button is no longer depressed, the actuator follow the 

signal from a control system or a built-in positioner.

Tip:

 If the manually set position is to be maintained, ensure that the input signal    

 

 

from the control system or positioner is deactivated.
