The shut-off valve assembly comprises a valve housing and a valve member disposed within a valve chamber defined by the valve housing. When the conduit assembly is in the closed configuration, pressurized air within the valve chamber forces the valve member into a closed position against the valve housing to prevent pressurized air from reaching the mixing location. When the conduit assembly is in the open configuration, it displaces the valve member into an open position in which pressurized air can flow from the valve chamber, through the conduit assembly, and to the mixing location.

To facilitate cleaning and to allow the gun to spray in an upward direction, the paint may be sealed in a collapsible closed bag located in the cup. With the closed bag and the suction feed, the gun will operate when aimed in all directions. The gun is easily cleaned by forcing solvent from the nozzle assembly back into the bag and disposing of the bag containing any remaining paint and the used solvent.
