ABSTRACT:
A solenoid valve for a water purification system. The solenoid valve contains a fluid valve which can move between an opened position and a closed position, and a coil which moves the valve to the open position when a first voltage is supplied to the coil and maintains the valve in the open position as a second voltage is supplied to the coil. The coil is coupled to a control circuit which initially supplies the first voltage to the coil when the valve is to be opened, and then reduces the first voltage to the second voltage after the valve is in the open position.
