This patent describes a method of controlling the passage of material through a structure of the type which includes valve body means defining a valve chamber and having an inlet port and an outlet port each communicating between the valve chamber and the exterior of the valve body means; annular inlet seal means in the valve chamber and having an inlet passage therethrough communicating in seal engagement with the inlet port; annular outlet seal means in the valve chamber and having an outlet passage therethrough communicating in sealing engagement with the outlet port; valve member means for controlling the passage of material through the valve body means. The valve member means having a frustoconically shaped outer surface and being disposed within the valve chamber with the frustoconically shaped outer surface in close slidable sealing engagement with the annular outlet seal means and being adapted to rotate about its longitudinal axis within the valve chamber; the method comprising the steps of: (a) introducing fluid generally transversely into the inlet port at a point upstream of the annular inlet seal means; (b) supplying material to the inlet port upstream of the point of introduction of the fluid; and (c) rotating the valve member means relative to the valve body means to block flow of the material and the introduced fluid through the valve body means from the inlet port, and, alternately, to permit flow of the material and the introduced fluid into the valve body means via the inlet port and out of the valve body means via the outlet port.
