Abstract

A Y-shaped flow splitter passes papermaking fluid with some fibers with reduced clogging and has a flat surface opposite the leg of the Y where the flow divides into the two arms of the Y. A generally flat rectangular surface is positioned opposite the leg of the Y of the flow splitter which divides the flow evenly without providing a place for fibers to collect and thus clog the flow through the splitter. The splitter allows the flow to a pair of dilution tubes to be controlled by a single valve with a single flow passage reducing clogging and valve cost. The flow splitter is constructed of stainless steel by a by casting process. A process known commercially as the Extrudehone process is used to produce smooth flow passages.
