Attachments Function
Functional description
The actuator moves the blades of a multileaf damper into OPEN or CLOSED
position.
Electric spring return actuator
Control input signal with 2-wire control (3-point).
Double acting pneumatic actuators
The easiest way to generate the control input signal is electrically, using
solenoid valves.
The multileaf damper is opened and closed with compressed air. For this
purpose, the actuator has two tube connections. Compressed air is applied to
one tube connection while the other connection remains open such that the air
can escape from the corresponding chamber of the actuator. For the other
direction of rotation, the process is reversed.
Single acting pneumatic actuators
The easiest way to generate the control input signal is electrically, using
solenoid valves.
The multileaf damper is closed with compressed air and opened with spring
force. The actuator has one tube connection. This tube connection is for
compressed air. For the other direction of rotation the connection remains
open.
