AUMA MATIC multi-turn actuators operate valves at the Killylour water works in Great Britain
AUMA multi-turn actuators SA fulfill a high standard for the operation of valves
  • robust design
  • high class of enclosure
  • reliable operation
  • wide torque range
  • fine progressive ratio (factor 1,4) of output speeds from 4 to 180 rpm (up to SA 16.1 from SA 25.1 lower max. speeds)
  • mounting in any position possible
  • easy commissioning
  • low service requirements
 
  Multi-turn actuators with integrated actuator controls
AUMA MATIC

As an option multi-turn actuators SA and SAR up to size 16.1 can be equipped with the AUMA MATIC actuator controls.

The application of actuator controls AUMA MATIC offer advantages during:

  • project design
  • valve automation
  • start up and commissioning
  • operation

In many cases, integral actuator controls provide a more cost-effective solution than remote motor controls.

   Multi-turn actuators SA 07.1 - SA 16.1 SAR 07.1 - SAR 16.1 with actuator controls AUMA MATIC

 
  Multi-turn actuators with adjustable output speed and  electronic controls VARIOMATIC

The multi-turn actuators SARV 07.1 - SARV 10.1 show the following advantages in comparison to conventional actuators:

  • output speed adjustable
  • high number of starts possible
  • Type of duty S5 - 40% ED
  • braking after switching off, i.e. no overrun
  • 1 ph power supply 220 - 240 V for 50 and 60 Hz
  • internal electronic positioner (option) reduces output speed when approaching the nominal value

   Multi-turn actuators SARV 07.1 SARV 10.1 consisting of the multi-turn    actuator SAR, the electronics control VARIOMATIC and the electronically commutated motor
