High voltage high efficiency valve

A zone valve control system for a valve that is capable of being opened and closed to flow to an external zone, the control system comprises a direct current rotary electric motor having a connection to a primary source of DC current and an output shaft, the DC polarity determining the direction of rotation of the output shaft;

• the system further comprising:
• an electronic control system comprising a microprocessor for controlling the connection between the electric motor and the source of DC current, an electric measuring device capable of measuring the electric current connected to the electric motor, and sending a signal to the microprocessor when a predetermined value is detected, and at least one rechargeable electrical storage system, the at least one rechargeable electrical storage system having a total storage capacity sufficient to power the DC electric motor to fully open or close the valve, the at least one rechargeable electrical storage system being capable of receiving and storing DC current and to discharge such current to the motor having a reverse polarity from the polarity of the power from the primary source of DC current;
• the microprocessor further being capable of receiving and processing an electrical signal from an external sensor for signaling when a certain condition exists in an external zone, and from the electric measuring device for signaling that a predetermined electrical current is flowing to the motor;
• the microprocessor being capable of controlling the flow and polarity of DC current to the motor when a predetermined signal is received from the external sensor that a desired condition does exist not in the external zone in order to cause the valve to move in a first direction to open the valve to change the condition in the zone, or to reverse the polarity of the current upon receiving a signal that the desired condition exists in the external zone, so as to cause the motor to cause the valve to move in the reverse direction to close the valve;
• and when a predetermined signal is received from the electric measuring device signaling that a predetermined current is flowing to the motor, indicating that the valve cannot move further, to shut off the current flow to the motor;
• whereby the electronic control system controls movement of the valve operably connected to the electric motor output shaft, to close or open a valve to maintain or produce a desired predetermined condition in the external zone.
