The motor triggered by the power electronics controls the drive shaft via oil-lubricated spur
gears. This transmits the torque to the valve via a lever with ball-and-socket joints and a
coupling rod. A position sensor detects backlash-free the current position of the drive shaft.
Adjustable limit stops prevent overloading of the valve in the event of an operating error. The
motor brake locks the actuator in the current position if the power suplly is cut off.
