  • Patent number: 6755214
    Abstract: A control valve system including a housing having an inlet, a first output, and a second output. The control valve system further includes a slidable valve positionable in a first position, where fluid communication is established between the inlet and the first output; a second position, where fluid communication is established between the inlet and the second output; and a third position, where fluid communication is prevented between the inlet and the first or second output. A solenoid valve assembly is coupled in fluid communication with the inlet and is positionable in an actuated position, where fluid communication is established with the inlet to move the valve from the first position to the second position, and a deactuated position. A piston selectively extendable to position the valve in the third position in response to fluid pressure within the first output.
