Abstract
A valve assembly is provided for use in controlling the maximum flow of a pressurized fluid through a hollow body. The hollow body includes a fluid inlet and a fluid outlet separated from one another by a partition having an aperture formed therein. The valve assembly includes a sleeve member which is disposed within the hollow body so that one end of the sleeve member is disposed adjacent to and in substantial alignment with the partition aperture. The sleeve member is provided with a discharge port which is spaced from the one end and is in communication with the fluid outlet. Sealingly engaging the portion of the partition defining the aperture is an adjustable seating piece. An elongated valve stem is mounted within the sleeve member for axial movement between open and closed positions. Encompassing the exterior of the sleeve member adjacent the one end is a flow control element which is provided with at least one opening, the latter being adapted to assume selected relative positions with respect to said discharge port so as to vary the effective size of the latter. The control element is adjustable to a selected relative position only when the valve assembly is removed from the hollow body and the valve stem assumes its open position. The control element and the sleeve member one end are provided with complemental means which coact with one another and restrain rotation of the control element relative to the sleeve member one end once the control element is in a selected relative position.
