<p>An orifice flow control valve is provided with a set of 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 and in face-to-face engagement concentric with the downstream disk. There are holes in the downstream disk and in the upstream disk for control of the amount and direction of flow of fluids through the valve. When the valve is in a position between fully open and closed, there are at least two streams through the disks which impinge on each other for providing a resultant stream flowing generally parallel to the axis of the valve.</p> |
