A liquid spray module which can be individually used, or which can be easily mounted in ganged side-by-side relation with a plurality of such modules. Each module includes a spray gun cartridge having liquid passages through the liquid to be sprayed, is directed and one or more air passages through which pressurized air may be directed for assisting in atomization of the liquid and controlling operating movement of a valve needle. Each spray gun cartridge further includes a manifold body having a central bore into which the spray gun cartridge is removably mounted and liquid and air inlet and outlet passages which communicate with the liquid and air spray gun cartridge passages. The spray gun cartridge is removable from the manifold body without disconnection of fluid supply lines to the manifold body and without removal of the manifold body from a ganged mounted array of such spray modules.
