Auma SQEx .2 part-turn explosion-proof actuator

Auma has announced the availability of its SQEx .2 part-turn actuator. The product is the explosion-proof version of the company’s SQ actuator.

The SQEx .2 meets the European ATEX and International IECEx standards and will be submitted for certification in additional countries including the Russian Federation, the United States, Japan and Canada.

An explosion-proof SQREx version for modulating duty is also available from the company, providing enhanced positioning accuracy and an increased number of permissible starts per hour.

Designed for butterfly and ball valve automation, the SQ and SQEx ranges replace the company’s established SG and SGExC part-turn actuator ranges. Compared with the predecessor product, the SQ series offers a significantly wider torque range, covering 50 to 2400 Nm. Further enhancements include sophisticated diagnostics and asset management functionality.

Commissioning and operation of SQEx actuators are identical to the company’s SAEx multi-turn actuator line. Both ranges are available with simple AMExC or micro-controller operated ACExC integral controls - controls are therefore interchangeable and, at plants where both product series are installed, on-site device management is simplified.
