Modulating actuators SAR
Multi-turn actuators SAR 07.2-16.2 (Generation 2 version; 15Nm~1,000Nm) and SA 25.1 - SA 48.1 (1,000Nm~4,000Nm)

Regarding to General 1 vesion (SAR 07.1-SAR 16.1 ), Available spare parts can be purchased smoothly.
GENERATION 2 IMPROVEMENT
Multi-turn actuators Generation .2


Improved handling and operation
Convenient connection facility due to enlarged electrical connection via
AUMA plug/socket connector by using large cable entries.
The AUMA motor plug/socket connection is now available across the complete
Generation .2 series. The compact design results in reduced weight at comparable
torque. Improvement of the approved AUMA handwheel activation by applying
a spring-loaded system with manual operation indication.
AUMA control unit in electronic and mechanical version with adjustable reduction
gearing for conventional stroke ranges.

Intelligent diagnostic function and sensor system
In combination with the electronic control unit, temperature and vibration sensors for monitoring the service parameters guarantee reliable operation and allow preventive maintenance for Generation .2 multi-turn actuators.

Precision and control accuracy
An enhanced mechanical structure and reduced mechanical tolerances have lead to improved control accuracy and an extended output speed range for modulating actuators.

Permanent reliability
Material selection, construction and new manufacturing methods as well as the further enhanced corrosion protection ensure higher service life.

Flexibility and adaptation
The valve connection for Generation .2 multi-turn actuators implemented as standardised hollow shaft, plug sleeve solution - allows significant flexibility for valve adaptations.
Multi-turn actuators SAR 07.2-SAR16.2 and SAR25.1 - SAR 30.1 are designed for intermittent duty S4 - 25%.  Special versions for S4 - 50% and S5 - 25% are also available.
