Abstract
A three-way rotary plug valve comprising upper and lower radial arms carried on top and bottom shafts and supporting an integral arcuate closure member between them. The upper shaft extends through a bearing in the top closure and carries a sector position indicator having an arcuate outer surface which overlies and is coextensive with the arcuate closure sealing surface so that the precise position of the closure is apparent at all times. Marks on the top cover depict the locations of the flow passages and cooperating stop means on the cover and the position indicator prevent complete blockage of the inlet passageway from the pump.
