Abstract
A manifold block for controlling the flow of liquids and useful in the application of paint to automotive vehicles and in other, similar, applications is provided. The manifold block houses at least one liquid inlet supply channel, at least one liquid outlet return channel, and an applicator channel in microvalved connection with the inlet channel and the outlet channel, which channels meet at a common intersection in adjacent proximity to the microvalve. Stagnation in any of the channels in either the “open” or “closed” mode of operation of the microvalve is substantially eliminated. A stacked array of a plurality of these manifold blocks may be interconnected through a common applicator channel.
