ABSTRACT:
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.
