Rotary actuators with spring return

Rotary actuators with spring-return

Electronic motor driven actuators for 2-position, 3-position, and modulating control, with spring return. Type-specific variations with adjustable offset and span for the positioning signal, position indicator, feedback potentiometer and adjustable auxiliary switches for supplementary functions are available.

Typical use:

  • The dampers are friction-dependant and for damper areas up to 3 m2

  • In ventilation sections where the actuator must move to the zero position (emergency position) during power failure

  • For dampers having two actuators on the same damper shaft (tandem-mounted acuators or powerpack)
