ABSTRACT:
A multiple orifice flow control valve has a set of similar disks mounted in the body of the valve. A downstream disk is mounted in a fixed position in the valve body and an upstream disk is rotatable in the valve body in concentric face-to-face engagement with the downstream disk. There are two holes in the downstream disk and two holes in the upstream disk for control of the flow of fluids through the valve. The two holes in each disk are at non-adjacent apexes of a regular pentagon. By rotating the upstream disk 72.degree. in one direction the valve changes from closed to one-half open. By rotating the upstream disk through the same angle in the opposite direction, the valve changes from closed to fully open.
