Abstract
This invention is directed to a flow diverter valve for directing a flow of high pressure transport gas with carbon dioxide pellets entrained therein from a single inlet to a selected one of a plurality of outlets. The flow diverter valve includes a system of face seals and shaft seals adjacent the inlet and outlet ends in order to prevent the leakage of high pressure gas from the flow path.
