A continuous fluid-solid contacting apparatus, comprising: a plurality of chambers (20) for containing the solid, each chamber having a supply (22) and a discharge conduit (24) for the fluid; a rotatable frame (30) for supporting the chambers (20); means (34, 36) for rotating the frame about an axis of rotation (A); a single valve (40) for controlling a supply and discharge of at least one fluid to the chambers (20), characterized in that said valve comprises: an annular disk (50) having a planar surface forming a disk valve face (54) and a plurality of conduits (44, 46) formed in the disk, the conduits extending to the planar surface to form openings in the disk valve face, a rotatable annular plate (72) having a planar surface forming a plate valve face (74) and a plurality of holes (76) forming ports in the plate valve face, the plate valve face contacting the disk valve face, a plurality of supply and discharge pipes (80, 82) connected to the plate on a surface opposite the planar surface, each pipe communicating with one of said holes (76) and connected with one of a supply and discharge conduit (22, 24) of the chambers, means (112, 114, 115, 117) for rotating the annular plate (72) about the axis of rotation (A) of the frame (30). <IMAGE>
