Abstract
A system for actuating an electrical valve from a remote location with a battery includes an energy storage means for actuating the valve, a charging circuit for charging the energy storage means from the battery to a sufficient potential to actuate the valve, detector means for sensing a signal indicative of a desire to actuate the valve and for actuating said charging circuit and switch means for connecting the energy storage means to the valve to actuate the valve when the energy storage means is charged to a sufficient potential.
