Rotary actuators without spring return

Rotary actuators without spring-return

Electronic motor driven actuators for 3-position and modulating control. Type-specific variations with adjustable offset and span for the positioning signal, position indicator, feedback potentiometer, self-adaption of rotational angle range and adjustable auxiliary switches for supplementary functions.

Typical use

  • The dampers are friction-dependant and for damper areas up to 6 m2

  • Suitable for use with modulating controllers (DC 0…10 V) or 3-position controllers for air dampers or air throttles
