A fluid atomizer or "air mist" nozzle or valve of this invention has an elongated nozzle body provided with a frontal exit port, a needle valve coaxially moveable therein and normally biased against a spring means so that its outlet end is just upstream of the nozzle exit port. The nozzle body is connected to a source of both water and air, as in the prior art. In this invention, the needle valve outlet position is controlled, vis-a-vis the nozzle body exit port, from the front of the fluid nozzle by providing a frontal control means for moving the nozzle body with respect to a fixed-in-place needle valve. The frontal control means is provided with both a rotatable and an axial motion and comprises preferably a control knob or ring threadably engaging the nozzle body near the frontal end thereof. The control knob is, in turn, mounted within a fixed flange plate, having a rearwardly extending cylindrical bore, for slideable axial movement within said cylindrical bore.
