Abstract
A control valve includes a main valve spool movable to a plurality of positions. A detent mechanism with a plurality of operational modes operates to releasably hold the main valve spool in displaced positions. An operator-controlled selector mechanism is coupled to the detent mechanism and is operable to selectively place the detent mechanism in a selected one of its operational modes.
