ABSTRACT:
A discharge valve for granular materials is disclosed which includes a valve body and a disc pivotally supported within the body. The arrangement is such that the disc rests against the body when the valve is closed to provide a seal therewith, and is pivoted by a resiliently biased handle to a plurality of open positions for controlling the flow of material through the valve.
