Abstract
Examples are provided that describe a linear hydraulic valve. In one example a linear valve comprises a sleeve with a plurality of ports spaced apart from each other at a distance. The plurality of ports are associated with a plurality of pressurized fluids. A spool comprising a plurality of openings that correspond to the plurality of ports is provided within the sleeve. The plurality of openings are spaced apart in a manner that enables alignment of a given opening of the plurality of openings to a given port of the plurality of ports based on a given position of the spool within the sleeve. The linear valve comprises an actuator for moving the spool in a forward or reverse linear motion along a longitudinal axis of the sleeve. The spool may be moved to a given position based on selection of a pressurized fluid of the plurality of pressurized fluids.
