Product description

Applications
AUMA multi-turn actuators are used wherever the automation of a valve requires rotation, e.g. when using gate
valves. The actuators can be adapted to suit the requirements ofnearly all valve applications. This is achieved by:

■

an extremely wide torque range,

■

various combination possibilities with AUMA valve gearboxes and controls,

■

a large variety of versions.

Solutions for a world in motionThis brochure will provide both the beginner and the
expert with an overview of the functions and applications
of AUMA SA/SAR multi-turn actuators. It is used as the
basis to determine whether a device is suitable for the
chosen application.
For detailed product selection refer to the separate data
sheets and price lists. On request, AUMA engineers within
field service and within oursubsidiaries can help you find
the correct device for the application.

The latest detailed information on the SA and SAR
multi-turn actuators can be found on the Internet under
www.auma.com. All documents, including dimensional
drawings, wiring diagrams and final inspection records (for
supplied multi-turn actuators) are available on the Internet
in a digitalised form.

The SA/SAR multi-turnactuator version has been available since 1986. Ever since, the actuators have been continuously improved. They can be combined with the latest
generation of AUMA actuator controls – enabled by the
modular design principle of the AUMA product range.
Both the mechanical interfaces as well as options for integration into a DCS are always up to date.

Applications/duty types
AUMA automates valves; to put it in a nutshell, this is
what AUMA actuators do. In other words: AUMA actuators
can be used for remote control of valves; either by an operation command manually triggered in the control room or
within the framework of an automated process-controlledprocedure. AUMA is an actuator specialist.

OPEN-CLOSE duty and positioning duty
OPEN-CLOSE duty
The valve is operated relatively seldom, the time intervals
can span between a few minutes up to several months.

According to the different valve designs, there are
multi-turn, part-turn and linear actuators. This brochure puts
the focus on multi-turn actuators. Multi-turn actuators are...
