Terminal 5 input only Z1EX

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.
