Non spring-return actuators
This chapter provides information on application, functions, and device combinations.
Furthermore, it contains a type overview and explains the actuator design including
setting and operator elements for this family of actuators.
The actuators are used in ventilating and air conditioning plants to operate air dampers
and air throttles:
For damper areas up to 3 m
Suitable for modulating controllers (DC 0...10 V) or three-position controllers
(e.g. for outside air dampers).
For dampers having two actuators on the same damper shaft (tandem-mounted
actuators or Powerpack).
