Abstract
Apparatus and associated methods relate to a transfer valve with dual authority control porting. The transfer valve has a hydraulic cylinder having a cylindrical wall extending between first and second ends. The cylindrical wall has hydraulic ports therethrough for facilitating operation of the transfer valve. Within the hydraulic cylinder, a bilaterally moveable spool is axially moveable between first and second positions. The bilaterally moveable spool defines hydraulic chambers within the hydraulic cylinder. In the first position, the hydraulic chambers and the hydraulic ports form a fluidly conductive path between a first source and a first application, and another between a second source and a second application. In the second position, the cavities and the hydraulic ports form a fluidly conductive path between the first source and the second application, and another between spool positioning cavities of the transfer valve and the first application.
