Product Overview

The AUMA SA & SAR electric actuator series represents modular, all-round solutions for valve automation. The SA series rotary actuators are specifically designed for control and positioning duty (classes A and B), typically operating in short-term duty (S2 - 15 min), with a special version for S2 - 30 min available for longer running times. The SAR series actuators are multi-turn units designed for modulating duty (Class C), rated for S4 - 25%, with special versions for S4 - 50% and S5 - 25% also available. These actuators can be combined with various control units, from simple OPEN-CLOSE functions to sophisticated microcontroller-controlled versions with fieldbus interfaces and operating data acquisition.

Key Benefits

• Expansive Torque Range: Covers 10 Nm to 32,000 Nm for versatile control operations.
• Enhanced Duty Cycles: Supports up to Class C modulating duty and offers extended short-term duty options (S2 - 30 min).
• Advanced Control: Modular design allows for combination with various actuator controls, including those with operating data acquisition and fieldbus interfaces.
• High Reliability: Features the highest protection class, wide temperature range, and high-quality corrosion protection.
• Functional Safety: Use up to SIL 2 is possible in selected configurations.

Applications

• Designed for control (Class A and B) and modulating (Class C) duties in valve automation.
