Abstract
A trailer control valve for a tractor includes a body defining a supply port and first and second delivery ports. The supply port is configured for fluid communication with a fluid source on the tractor. The first and second delivery ports are configured for fluid communication with glad-hand connectors through which fluid is supplied from the tractor to a trailer. A pressure sensing solenoid receives fluid signal from each of the first and second deliver ports and selectively passes fluid signal therefrom to a pressure sensor as a function of a brake control signal received by a controller that controls the pressure sensing solenoid.
