AUMA returned to Wasser Berlin to present its extensive range of electric actuation products supplied to the water industry. A central exhibit for the modular actuation experts will be company’s new SQ .2 part-turn range for butterfly and ball valve automation. The actuators will replace AUMA’s established SG .1 range manufactured since 1998.
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. A new actuator size included in the SQ .2 series more than doubles the torque range previously offered by AUMA’s predecessor product – the SG .1: this represents a significant expansion now covering 50Nm to 2,400Nm. 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. 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.
