HVLP spray gun capable of operating from a source of high pressure air. Compressed air is delivered to the gun through a relatively small diameter air hose. A pressure compensated control valve is mounted in the spray gun to reduce the air pressure delivered to an air/fluid nozzle to a predetermined pressure of no greater than 0.7 Kg/cm.sup.2 (10 psig). The control valve maintains a constant air pressure at the nozzle when either the atomization air flow rate is changed and/or the fan air flow rate is changed of the pressure of the source air changes.

Pressure compensated HVLP spray gun

A color changer comprises a manifold assembly including first and second fluid outlet passages for supplying coating material to first and second devices, respectively, a coating material circulation line extending through the manifold assembly, and valves for selectively coupling the coating material circulation line to the fluid outlet passages for separately controlling flow of coating material from the circulation line to the first and second outlet passages. The valves are coupled to the manifold assembly. The valves are arranged in pairs, one valve of each pair disposed across a respective coating material outlet passage directly opposite the other valve of its respective pair. The manifold assembly comprises a plurality of segments which are joined together to form the manifold assembly. At least a portion of each coating material circulation line is provided by a respective segment and the valves are removably attached to the segments to permit removal and replacement of a valve without disconnection of a respective coating material circulation line.
