FQM and FQMEx fail safe unit

With their new FQM fail safe unit, AUMA offer innovative and safe actuator solutions for automatic operation of valves in case of emergencies making use of stored mechanical energy.

 

Constant torque curve with torques from 150 Nm to 1,200°Nm

 

The spring is not operated during standard operation. Thanks to the overriding gear arrangement, the constant force spring is disengaged during normal operation and does not need to be operated.

 

The end position switches are automatically set during the setting procedure of end positions OPEN and CLOSED and do not require separate adjustment.
