ABSTRACT:
A rotary valve apparatus having particular utility to the valving of high solids content fluids such as slurries and the like provides a normally fixed, generally flat circular disk defining a valve body and providing a plurality of radially spaced flow openings and an open center. A generally flat valving member is mounted in face-to-face engagement with the disk and is movable with respect to the disk between open and closed positions. The valving member provides a hub with a shaft opening therethrough and a plurality of radially projecting valving members which align with and cover the flow openings in the closed position. A common shaft penetrates the open center and the shaft opening and affixes at one thereof to the valving member for rotation therewith. The common shaft is generally coincident with the central axis of the valve body and is entirely disposed within the fluid flow stream being valved. A pneumatically operative vane affixed to the common shaft at the opposite end portion thereof from the valving member moves with the shaft through equi-angular rotation. A vane housing is mounted rigidly by brackets, for example, on the circular disk body and about the vane with the housing providing stops defining the extent of angular movement of the vane. Movement of the vane between the stops correspondingly moves the valving member between open flow and closed flow positions.
