New AUMA Actuators Offer Significant Torque Advancement

auma sq.2AUMA is extending its portfolio of modular electric actuators to include an SQ.2 part-turn range for butterfly and ball valve automation.

Scheduled for launch in 2013, the actuators will replace the company’s established SG.1 range manufactured since 1998.

A new actuator size included in the SQ.2 series more than doubles the torque range previously offered by the SG.1: this represents a significant expansion now covering 50Nm to 2400Nm.

Other developments include the introduction of an SQR version for modulating duty which replaces the SGR. The SQR provides improved control characteristics with enhanced positioning accuracy and an increased number of permissible starts per hour.
