Orders accepted for new AUMA actuator

AUMA, the established manufacturer and global supplier of modular electric actuators, has announced that orders can be placed for its new part-turn actuator.
Designed for butterfly and ball valve automation, the SQ .2 replaces AUMA’s established SG .1 range. Enhancements set to expand process control applications for AUMA in the power and water industries include a significant increase in torque range, sophisticated diagnostics and asset management functionality. A new actuator size in the SQ .2 series more than doubles the torque range offered by AUMA’s predecessor product: this is a significant expansion now covering 50Nm to 2,400Nm.
Advanced features and benefits include adoption over a wider torque range without the need for a gearbox – this provides a more compact and cost effective actuation solution. Sophisticated diagnostics and asset management enhancements include additional temperature and vibration sensors. For enhanced positioning accuracy, and an increased number of permissible starts per hour, an SQR version for modulating duty replaces the SGR. Commissioning and operation of SQ actuators are identical to the SA .2 multi-turn range, introduced by AUMA in 2010.
Both ranges are available with simple AM or micro-controller operated AC integral controls – as a result, controls are interchangeable and, at plants where both product series are installed, on-site device management is simplified. Orders for SQ actuators for three-phase applications can be placed from February 2013 with delivery from April. SQ actuators for single-phase or Ex installations will be introduced in the second half of the year.
