Abstract
A zone valve control system for a flow valve comprising a direct current rotary electric motor connected to a valve shaft, an electronic control system comprising a microprocessor, an electric measuring device for signaling the presence of a predetermined electrical stall current, a rectifier and a regulator to convert and regulate external AC voltage to a desired DC power output; and an electrical storage system having a total storage capacity sufficient to power the DC electric motor to move the valve between the closed and opened positions; an external sensor for signaling when a certain condition exists in an external zone; the microprocessor controlling the flow and polarity of DC current to the motor; whereby the electronic control system controls movement of a valve operably connected to the output shaft to open or close a valve to maintain a desired predetermined condition in the external zone.
