Auma, the German-based supplier of modular electric actuators to the power industry, has announced 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 SG.1 range, manufactured since 1998, the announcement added.

According to Auma, the new two-component powder coating has been incorporated into the SQ.2 design, ensuring improved corrosion protection, and the enclosure protection of the devices meets IP 68 – basic standards.

The manufacturer lists the following product features and advantages:

  • The 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 2,400Nm.
  • It also comes with 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 type range, introduced by Auma in 2010. This includes the same control concept: the two ranges are without integral controls and are available with simple AM or micro-controller controlled AC. As a result, controls are interchangeable and, at plants where both product series are installed, on-site device management becomes simplified.
