ABSTRACT:
A multiple inlet multiple outlet rotary plug valve includes a valve body having two sets of ports at different elevations. Each set of ports includes three ports one of which is an inlet. A cylindrical plug is disposed within a cylindrical bore of the valve body. The plug has a discrete passage for each set of ports. Each plug port is dimensioned so that flow from an inlet can be directed to each outlet of its set in one position of the plug.
