ABSTRACT:
A free-flowing granular material storage bin of the type having an inflatable dual-walled, cup-shaped bag with a fan for inflating and deflating the bag has a single valve assembly of unique construction for controlling high volume low pressure flow for inflation and deflation cycles. The cycles are themselves automatically controlled from sensing units which sense when the bag is fully emptied and fully deflated.
