With the FQM fail safe unit, AUMA offers innovative and safe actuator solutions for automatic operation of valves in case of emergencies making use of stored mechanical energy.
Constant torque characteristics across the overall torque range.
The spring is not operated during standard operation. As a consequence, actuator sizing can be relatively small.
The end position switches are automatically set during the setting procedure of end positions OPEN and CLOSED and do not require separate adjustment.
