Abstract: An example valve includes: a sleeve having a plurality of sleeve openings; a first conduit configured to be in hydraulic communication with a first chamber, where a first pressure sensor is disposed in the first conduit and configured to measure a pressure level of fluid in the first chamber; a second conduit configured to be in hydraulic communication with a second chamber, where a second pressure sensor is disposed in the second conduit and configured to measure a pressure level of fluid in the second chamber; a spool rotatable within the sleeve, wherein the spool includes a plurality of spool openings respectively corresponding to the plurality of sleeve openings; a rotary actuator coupled to the spool and configured to rotate the spool within the sleeve in clockwise and counter-clockwise directions; and a controller configured to cause the spool to rotate to one of a plurality of rotary positions.
