A spray nozzle configured to be disposed on top of and coupled to a standard spray paint canister. Compressed gas within the spray paint canister serves as the propellant which expels the liquid paint out of the canister when the nozzle is actuated. The paint and compressed gas travel through the internal passageways of the nozzle and are ejected from the nozzle in a three-dimensional conical discharge. The nozzle comprises an adjustable valve for a user to manipulate and change the emitted three-dimensional discharge from the canister. The adjustable valve alters the internal flow characteristics of the nozzle which in turn change the diameter of a circular spray pattern which is produced when the nozzle is held at a set distance away from a surface that is being sprayed. The user may adjust the fluid flow during use or between uses.
