Abstract
An electric control valve for a heavy duty vehicle air parking brake system. The system uses latching electrically controlled solenoid air valves to control the parking brake systems of the tractor and trailer. The system allows electric control devices to be placed in the vehicle's instrument panel. The system maintains a previously set state of the system even in the event of a loss of electrical power to the controller. Indicator lamps provide park status information to the vehicle driver.
