Electric actuators for throttle dampers: These quarter-turn actuators automate the opening, closing or modulating positioning of a suitable throttle damper. Their 0 to 90° rotation range matches typical damper movement.

The range includes a 24 V DC version with 45 Nm and 230 V AC versions with 50 Nm. All variants have an aluminum housing, IP67 protection and DIN ISO 5211 F03/F05 flange connections.
