Claim 7:
8. An air control valve system for routing compressed air from a semi-tractor into a tractor trailer to pressurize the tractor trailer for discharging a liquid stored in the tractor trailer, said system comprising:
a semi-tractor having an air brake system, said air brake system has an output port wherein said output port is configured to output compressed air produced by said air brake system;
a tanker trailer being configured to contain a liquid, said tanker trailer has an air input being integrated into said tanker trailer wherein said air input is configured to facilitate air to be directed into the tanker trailer;
a gladhand air fitting being fluidly attachable to said air brake system, said gladhand air fitting has an input and an output, said input engaging said output port such that said gladhand air fitting is in fluid communication with said output port when said gladhand air fitting is fluidly attached to said output port;
a valve being fluidly coupled to said gladhand air fitting, said valve being positionable in an open position wherein said valve is configured to pass air through said valve, said valve being positionable in a closed position wherein said valve is configured to inhibit air from passing through said valve, said valve has a housing and a handle being rotatably coupled to said housing wherein said handle is configured to be manipulated, said housing having an inlet and an outlet, said inlet of said housing being fluidly coupled to said input output of said gladhand air fitting wherein said valve is configured to receive the compressed air from said air brake system; and
an air king fitting being fluidly coupled to said valve wherein said air king fitting is configured to receive the compressed air from said valve when said valve is in said open position, said air king fitting being releasably matable to said tanker trailer having said air king fitting being in fluid communication with an interior of said tanker trailer wherein said air king fitting is configured to pressurize said interior of said tanker trailer for discharging fluid contained in said tanker trailer, said air king fitting has an inlet and an outlet, said air king fitting having a pair of wings each extending away from said outlet, each of said wings releasably engaging said air input on said tanker trailer for releasably retaining said air king fitting on said air input, said input of said air king fitting being fluidly coupled to said outlet of said housing of said valve wherein said input of said air king fitting is configured to receive the compressed air from said valve.
