Part-turn actuator Definition according to ISO 22153:
AUMA part-turn actuator
A part-turn actuator is an actuator which transmits torque to the valve for less than one
revolution, and does not need to be capable of withstanding operational thrust.

The connection option for the tools (hexagon head or hexagon socket) for emer-
gency operation is located below the screw plug for manual emergency operation
[5]. The manual emergency operation is available without handwheel function for
sizes PF-Q20 and PF-Q40.
AUMA PF-M part-turn actuators are driven by an electric motor. For control in motor
operation and for processing the actuator signals, controls are integrated within the
housing. Push buttons allow for local actuator operation. A handwheel is provided for
occasional manual operation. Manual operation is possible without change-over.
The swing angle is limited by internal end stops. Seating in end positions is either via
limit seating or torque seating.
The self-locking of the actuator is ensured by means of the braking function. As soon
as the actuator is at standstill, the motor takes over the brake function for the first 20
seconds. This period is defined through a parameter which can be set via Bluetooth.
After this, the locking brake takes over the brake function by disconnection from power
and renewed engagement. Brake engagement generates a noise and is part of the
standard operating behaviour.
The actuator is equipped with a torque measurement feature. The measured values
can be read by means of the AUMA Assistant App or AUMA CDT. Measurement val-
ues are generated during motor operation. No measured value is generated during
manual operation. The last measured value remains frozen and is displayed. This is
not the case when starting from a torque seating end position. In this case, the value
is set to zero and also displayed as zero.
