Abstract: A coating material color change system includes a manifold having a first passageway through which a selected color flows during its selection, a plurality of coating material passageways intersecting the main passageway, and an equal plurality of coating material supply valves mounted to the manifold. Each coating material supply valve has a body and a member movable in the interior of the valve body for controlling the flow of the coating material to be supplied by that coating material supply valve through a respective coating material passageway to the main passageway, and a mechanism for actuating the member. The mechanism is controllable by a superatmospheric pressure fluid signal selectively to control the position of the member and thus the supply of the coating material to the first passageway. The manifold and valve bodies include second passageways and means for coupling the second passageways to a source of operating fluid under superatmospheric pressure.

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.
