ABSTRACT OF THE DISCLOSURE: A switching valve for selection of different paths for a flow of particulate material, such as powdered and granular materials, when transported by a gas in a pneu- matic transport system for the particulate material. The switching valve comprises a housing with connections for an upstream conduit and a plurality of downstream conduits, and a rotor arranged for rotation within the housing and having radially extending surfaces axially opposite each other and a compartment with an open end at one raidal sur- face facing the mouth of the upstream conduit connection, a closed end toward the opposite radial surface, a radial extension within the rotor forming at least a portion of a discharge connection between the compartment and any one of the downstream conduit connections, and an axial extension within the rotor forming a blind space at its closed end for providing a cushion of the particulate material. Driving means rotate the rotor to position the discharge connection to open out the compartment into any one of the downstream conduit connections. There are means for supporting the rotor at the opposite radial surface for rotation within the housing. And a pneumatic transport system for particulate material, such as powdered and granular materials, with such a switch- ing valve for selection of different paths for flow of the particulate material when transported by gas.
