Variable operating time actuators SQVEx and SQRVEx
With SQVEx .2 part-turn actuators for open-close duty and SQRVEx .2 for modulating duty paired with ACVExC .2 actuator controls, the proven AUMA SQ/SQR range is enhanced by variable operating time models.
AUMA is spearheading market technology, offering a wide operating time range with a ratio of up to 1:10. Actuators of the SQVEx type range are rated for open-close duty and positioning duty (classes A and B) / (short-time duty S2 - 15 min). Actuators of the SQRVEx type range are rated for modulating duty (class C) S4 - 25 %
Design features SQVEx:
- Torque range from 150 Nm to 2,400 Nm
- Swing angle from 75° to 105°
