AUMA: Fail Safe Actuator
For applications with significant hazard potential in the oil & gas sector and other industrial markets, fail safe actuators are required.

A further special feature of the AUMA FQM innovation is variable running speed during fail safe operation. The soft end position approach of the valve is achieved by reduced speed. This also avoids pressure peaks within the pipeline and preserves the valve.
The new fail safe unit can be combined with AUMA SQ part-turn actuators or SA multi-turn actuators paired with GS part-turn gearboxes, both with AC controls. Operating concept, interfaces and communication with the DCS are identical to AUMA standard actuators. Due to AUMA’s modular design concept, the fail safe unit can be retrofitted within existing plants.
The AUMA fail safe unit is particularly suited to automation of butterfly valves and ball valves at an angle of up to 90°. The fail safe unit meets the requirements of safety-related applications up to SIL 2/SIL 3 and is virtually maintenance-free. An explosion-proof version is also available.
