1. A dual airflow control system for an environment having a first air zone and a second air zone, comprising:

  • a first input device operable to generate a first input signal indicative of a desired airflow to the first zone;

    a second input device operable to generate a second input signal indicative of a desired airflow to the second zone;

    first and second flow regulators configured to regulate airflow to the first and second zones, respectively, such that the first and second regulators selectively provide airflow to each of the first and second zones based on the first and second input signals, the first and second flow regulators each including a first plate having first orifices formed therein, and a second plate having second orifices formed therein, the second plate being configured to move relative to the first plate in a manner that the first and second orifices define passages configured to selectively open and close to regulate the airflow to the first and second zones; and

    a single actuator associated with the first and second flow regulators and operable to simultaneously actuate the first and second flow regulators independently based on an input from the first and second input devices to allow the desired airflows to the first and the second zones.
