AUMA SAR multi-turn modulating electric actuator, 15–4,000 Nm, S4-25%

AUMA SAR is the modulating version of the AUMA multi-turn series. The actuator holds intermediate valve positions and follows the setpoint for flow, pressure or level. It is rated for class C, S4-25% duty; special versions are available for S4-50% and S5-25%.

The SAR design is close to the SA: travel and torque sensing, handwheel, IP68 enclosure, KS corrosion protection and DIN/ISO attachment. It is combined with AC/ACV actuator controls for positioner, data logging and fieldbus. SAREx is available for hazardous areas and SARV / SARVEx for variable speed.

Key features:

• Modulating duty, class C, S4-25%
• S4-50% and S5-25% options
• AC/ACV controls with positioner and fieldbus
