Abstract: An atomizing nozzle (20) configured to convert a fluid (88) into a mist (92) for use in a misting system is provided. The atomizing nozzle (20) has a nozzle body (22) encompassing a cylindrical occluder chamber (50), a substantially spherical occluder (26) residing within the occluder chamber (50), and an orifice insert (24) affixed to an outlet end (44) of the atomizing nozzle (20). The orifice insert (24) encompasses an insert chamber (74) contiguous with the occluder chamber (50) and having a conical chamber bevel (76) proximate an outlet end (78) of the insert chamber (74), and has a mating surface (82) configured to mate with the occluder (26). The mating surface (82) has at least one flow-control groove (86) configured to control the flow of the fluid (88) through the atomizing nozzle (20).
