Abstract

There is provided a fluid rerouting system for valve bodies that use hydraulic pressure, via a balance pressure line, to move spools. In an exemplary embodiment, the system comprises a valve sleeve having a plurality of ports that are substantially aligned with a plurality of fluid connections in the mating bore, except that no valve sleeve port aligns with the balance pressure line. The system also includes a spool having a plurality of lands that are sized and configured to fit slidably in said valve sleeve. The combination of the valve sleeve and at least one of the lands form a chamber, fluid access to which is via an aperture traversing the land. Means for blocking the access of said balance pressure line to said valve sleeve are also included.
