FQM fail safe direction
Direction of rotation of FQM output drive shaft or the driven valve shaft when safety
function is triggered.
●
CW = Clockwise rotation
●
CCW = Counterclockwise rotation
Fail safe OPEN and fail safe CLOSE safety functions result from the overall
combination of actuator (gearbox), FQM and valve.

2.2. Short description
In emergencies, the fail safe unit is capable of closing or opening the valve
autonomously relying on mechanical functions. No electrical power is required for
such a fail safe operation. The torque required for opening or closing the valve is
generated by a constant force spring motor, providing a constant torque across the
total travel during fail safe operation. Consequently, the torque value for a fail safe
operation is determined by the available torque of the fail safe unit and is independent
from the actuator torque range.
For standard valve operation, the FQM fail safe unit is combined with an AUMA SQ
part-turn actuator. The required torque is transmitted directly from the actuator through
the fail safe unit to the valve. During standard operation, the constant force spring
motor of the fail safe unit is disengaged and is not operated.
The operating speed for the fail safe operation can be set in the factory. Furthermore,
the actuator operates the valve into the defined end position at reduced speed. This
avoids pressure peaks within the pipeline and protects the valve.
