● The actuators SQM45... / SQM48... are of robust design and have a gear train with only small backlash.            

● Control and position feedback take place via a bus system (CAN).

● The actuators are driven by stepper motors and can be positioned with a resolution of 0.1°.

● The running times of the associated controlling elements are varied by the basic unit depending on the burner’s control phase
