ABSTRACT:
A modular color changer provides selected paint colors for spraying and continuously recirculates both selected and non-selected colors. A module is provided for each color to be selected and includes supply and return manifold blocks defining, respectively, portions of a respective universal supply manifold and of respective universal return manifold. Port control valves are utilized to control paint flow therethrough, under normal supply pressures. Solvent and air purge valves are used for cleaning. The changer is particularly advantageous when used in high pressure spraying systems. Modules can easily be added to a basic changer to increase the number of selectable paints.
