摘要: A rotary valve for controlling the distribution of fluid flow to and from a number of vessels, such as filters, is adapted in one position to receive a single primary flow from a source, direct a separate fluid stream to each of several vessels, receive back a secondary fluid stream from each vessel and to dishcarge the combined secondary streams. Other positions of the valve effect blockage of the flow to any one of the vessels to isolate the same, passage to waste of the flow from the isolated vessel and restricted flow to the isolated vessel.
