2.2. Short description
Part-turn actuator
Definition in compliance with EN ISO 5211:
A part-turn actuator is an actuator which transmits a torque to the valve for less than
one full revolution. It need not be capable of withstanding thrust.
AUMA part-turn actuators are driven by an electric motor. A handwheel is provided
for manual operation. Switching off in end positions may be either by limit or torque
seating. Controls are required to operate or process the actuator signals.
Actuator controls
The AUMA MATIC actuator controls are used to operate AUMA actuators and are
supplied ready for use. The controls can be mounted directly to the actuator but also
separately on a wall bracket. The functions of the AUMA MATIC controls include
standard valve control in OPEN - CLOSE duty, position indications and different
signals right through to position control.
Local controls
Operation (via push buttons), setting and indication can be performed directly at the
controls (contents of these instructions).
