ABSTRACT:
An improved valve well-suited for controlling the flow of particulate solids comprises a valve body having a flow passageway comprising inlet and outlet passages extending transversely to a slide chamber. A plug member having a flow orifice, which is preferably of extended length extending transversely through it is mounted for sliding movement within the slide chamber to seal the flow passageway when the flow orifice is out of register therewith and to connect the inlet and outlet passages in flow communication when registered therewith. The flow orifice is preferably of ovoid cross-section and provides, at all operating positions of the valve, a cross-sectional flow area from the flow orifice to the outlet passage which is at least as great as the smallest cross-sectional flow area of the flow orifice. The flow orifice in its wide open position does not restrict the cross-sectional area available for flow between the inlet and outlet passages of the valve body.
