ABSTRACT:
A valve, primarily to control hydraulic flow, has a mounting tube ending in a disc spaced from the end of the tube to allow a flow passage. A polyjet sleeve, with multiple orifices through its wall, is axially slidable along the exterior of the mounting tube and on the exterior of the disc. An actuator, preferably hydraulic, moves the polyjet sleeve across the flow passage to vary the effective size of the flow passage.
