ABSTRACT:
An orifice valve is disclosed comprising a valve body having a cylindrical upstream chamber, a downstream chamber having an oblong cross-sectional configuration adjoining and coaxial with the upstream chamber, and a shoulder comprising a pair of blind holes at the juncture of the upstream and downstream chambers. A downstream disk having a pair of fluid openings is mounted in the upstream chamber against the shoulder and comprises a pair of blind holes aligned with the blind holes in the shoulder. Rigid pins extend from the blind holes in the shoulder into the blind holes in the downstream disk to prevent rotation of the downstream disk. A rotatable upstream disk having a pair of fluid openings is mounted against the downstream disk and comprises a pair of blind holes. An operator member is provided comprising a forked turning member with a pair of tines, each having a blind hole in alignment with a blind hole in the upstream disk. Rigid pins extend from the blind hole in the upstream disk into the blind hole in the disk engaging member. The operator member comprises a handle exterior the valve body for rotating the forked turning member and upstream disk.
