ABSTRACT:
Pre-set maximum-flow metering and mixing valves and methods of their operation, including limiting maximum axial (longitudinal) withdrawal of a valve metering stem corresponding to its minimally outlet-occluding location at fully open valve position. A sleeved member is threaded within a mating threaded end of a valve housing and about a mating end of an axially (longitudinally) adjustable flow-metering stem member to limit its travel (as by rotation) from seated fully closed position to a fully open position, corresponding to maximum withdrawal of its tapered end portion from its occluding insertion within the fluid outlet.
