Abstract:
A method for controlling a valve spool that includes providing a control valve having a first end and a second end with a spool disposed therebetween, a hydraulic component, a controller, a first control circuit and a second control circuit, selectively controlling the pressure in the first end and the second end with the controller, identifying an active state, with the controller, and applying an active pressure to both the first end and the second end with the corresponding first control circuit and second control circuit during the active state, and identifying a first command, with the controller, and providing a command pressure to the first end through the first control circuit and a release pressure to the second end through the second control circuit during the first command. Wherein, the spool is moved within the control valve and the hydraulic component is engaged during the first command.
