Definition in compliance with EN 15714-2/EN ISO 5210:
A multi-turn actuator is an actuator which transmits torque to a valve for at least one
full revolution.

AUMA multi-turn actuators SAVEx 07.2 SAVEx 16.2/SARVEx 07.2 SARVEx 16.2
are driven by an electric motor. A handwheel is available for setting and emergency
operation.
Switching off in end positions may be either by limit or torque seating.
Actuator controls are required to operate or process the actuator signals.
For non-intrusive version (control unit: electromechanical version), limit and torque
setting is made via switches within the actuator.
For non-intrusive version (control unit: electronic version), limit and torque setting is
made via the actuator controls, neither actuator nor the actuator controls housing
have o be opened. For this purpose, the actuator is equipped with an MWG (magnetic
limit and torque transmitter), also capable of supplying analogue torque feedback
signals/torque indication and analogue position feedback signals/position indication
at the actuator controls output.
In combination with output drive type A, the actuator is capable of withstanding thrust.
For variable speed multi-turn actuators SAVEx 07.2
SARVEx 16.2, the actuator speed is modified by means of a frequency converter in
the actuator controls.
Please note: Actuators in multiport valve product variant are multi-turn and can
approach different valve connection. Consequently, no end stops are available. The
designations used in the subsequent chapters "End position OPEN" and "End position
CLOSED" are equivalent to the MPV position or "Position reached".
The actuator controls ACVExC 01.2 may be mounted directly to the actuator or
separately on a wall bracket.
The actuator can be operated via the push buttons on the local controls of the actuator
controls or settings can be made in the actuator controls menu. The display shows
information on the actuator as well as the menu settings.
The functions of actuator controls ACVExC 01.2 include standard valve control in
OPEN-CLOSE duty, positioning, process control, logging of operating data right
through to diagnostic functions.
