ABSTRACT:
A flowable granular, powder or flake material storage bin of the type having an inflatable generally cup-shaped bag with a blower for inflating and a blower for deflating the bag has a valve assembly of unique construction for controlling high-volume low-pressure flow for inflation and deflation cycles. The cycles themselves may be automatically controlled from sensing units which sense when the bag is fully emptied and fully deflated. The valve assembly may be adapted for the sequential discharge of a plurality of bins which may, for example, be located on a freight vehicle.
