Abstract:
An example valve includes a sleeve having a plurality of openings. A spool is rotatable within the sleeve and includes a respective plurality of openings corresponding to the plurality of openings of the sleeve. A rotary actuator coupled to the spool is configured for rotating the spool within the sleeve to one of at least eight rotary positions. The rotary actuator can rotate the spool to a given rotary position in a clockwise or a counter-clockwise direction to cause at least a partial alignment between a subset of the respective plurality of openings of the spool and a subset of the plurality of openings of the sleeve.
