Abstract
An actuator for controlling the position of a damper. It is an adjustable damper actuator that can actuate a damper to have positions that are other than fully open and fully closed. The actuator has adjustable stops for attaining a partially closed or partially open damper as the operator wants. This actuator is useful for zone heating and air-conditioning as well as for providing a continuous supply of make-up air at low flow rates.
