ABSTRACT:
For use in an axial flow regulator which has an expandable sleeve changing the annular flow space around a central plug barrier to thereby moderate flow, a restricter which is installed to limit capacity. In the preferred and illustrated embodiment, the restricter defines a maximum flow through the apparatus which is calculated relative to the 100% capacity, and wherein the restricter comprises a means which fit next the flow regulator with an encircling cylindrical shoulder for anchoring purposes. It includes a transverse solid wall member. The transverse member is contoured to match cooperative equipment and to bolt to it. Moreover, the restricter is drilled with holes which regulate the flow capacity of the restricter and hence the axial flow regulator.
