HEATING VENTILATION AND AIR-CONDITIONING (HVAC) MODULE WITH A CURVED VALVE

A heating, ventilation, and air-conditioning (HVAC) module adaptable to balance air delivered by the module to distinct zones includes a valve. The valve is configured to rotate about an axis to variably restrict air delivered to a first zone and a second zone. The valve defines a curved portion characterized as curved about and offset from the axis by an offset amount. An increase to the offset amount decreases a first portion of air delivered to the first zone relative to a second portion of air delivered to the second zone.
