Actuators SA and SAR

Actuators of the SA type range for open-close duty and positioning duty are rated for class A and B or types of duty S2 – 15 min. A special version for longer running is available for the S2 – 30 min duty.
The modulating actuators of the SAR range are rated for class C or types of duty S4 – 25 %. Special versions for S4 – 50 % and S5 – 25 % are also available.
Actuators of type range SA/SAR 07.2 – SA/SAR 16.2 can be combined with various controls from simple OPEN-CLOSE control to the micro-controlled version with logging of operating data or fieldbus interface.

Combinations with worm gearboxes

By combining the multi-turn actuators SA with the worm gearboxes GS, they are turned into electric part-turn actuators for higher torque requirements. These combinations supplement the part-turn actuator ranges SQ whose torque ranges are limited to 2,400 Nm.

Design features
Torque range from 250 Nm to 675,000 Nm
Swing angles up to 100°
Operating times for 90 ° from 9 s to 392 s
adjustable end stops
self-retaining
Swing angles > 100° or multi-turn
(without end stops)
Electrical connection via AUMA plug/ socket connector (optionally terminals)
Plug cover with threads for cable glands
Output drive types according to ISO and DIN standard

Combinations with linear thrust units

To perfom linear movements, e. g. in case of globe valves, the multi-turn actuator SA can be combined with the linear thrust unit LE. In case a lever arrangement has to be operated, the linear thrust unit can be mounted on a base.

Thrusts from 4 kN to 217 kN
Strokes from 50 mm up to 500 mm
Speeds from 20 mm/min to 360 mm/min
Actuators SGC and SGCR

The “small” electric part-turn actuator range with integral controls.
All parameters are directly set at the actuator.
The controls contain switchgears, power supply unit, interface to the DCS. The component automatically switches the actuator off, once the valve end position is reached, motor overheating is detected or a torque overload has occurred.
All housing parts are made of aluminium. For this reason, the actuators are lightweight devices.
The actuators SGC are rated for class A and B or types of duty S2 – 15 min, the actuators SGCR for class C or types of duty S4 – 40%.
