Abstract
Disclosed is a double-slide valve for controlling a stream of fluid entrained particulate material. The double-slide valve comprises a valve body forming a closed chamber having an inlet opening, an outlet opening, and a pair of valve stem openings. Within the chamber is mounted a flow port having an entrance and an exit opening through which the stream of particulate material passes. The flow of this stream is controlled by two slidable valve plates which slide traversably across the flow port openings upon guide means. The amount of valve plate movement is controlled by a control means.
