ABSTRACT:
A high pressure fluid control valve comprises a body having an inlet, an outlet and a cavity disposed about a vertical axis. An outer cage having a plurality of radially disposed openings is sealably mounted in the cavity and has a vertical axis substantially aligned with the vertical axis of the cavity. An inner cage having a smaller diameter than the outer cage is sealably mounted in the cavity. The inner cage has radially disposed openings at its upper end, said upper end extending inside the outer cage thereby defining an annulus between the two cages. The inner cage has openings which are in fluid communication with the openings on the outer cage as well as the valve outlet. A plug operates partly within the annulus in a direction parallel to the vertical axis of the cavity and simultaneously restrict the radially disposed openings of the inner cage and the outer cage thereby regulating pressure drop or flow from the inlet to the outlet of the valve.
