A light-weight spray gun with an improved air control flow distribution to the spray gun nozzle is described, comprising a die-cast aluminium body (1) and a handle (2) of hard plastics material, the body having a spray head (3) and a nozzle (4) both of plastics material with weirs (5) providing an efficient baffling of the flow of air giving an even distribution of air to both the central atomising air to nozzle (4) and the flow of spreader air to horns (6) of the aircap. The weirs (5) are created by the profile of the spray head (3) and the external profile of nozzle (4). The aluminium body (1) is permanently joined to the outer profile of the plastics head (3) by a metal ring (10) to provide an efficient mechanical joint and seal between the parts. The invention includes an improved air distribution control valve.
