Abstract
A multi-port servo valve includes a valve plug within a valve body bore, where the plug has multiple holes radially positioned at different axial positions, and the bore has multiple ports, where the valve plug may be controlled to (i) align a first set of plug holes with a first set of bore ports to a first open position, (ii) align a second set of plug holes with a second set of bore ports to a second open position, and (iii) preclude alignment of the plug holes with the bore ports to a valve closed position. The system also includes a servo motor configured to control the position of the valve plug within the bore, and a programmable controller in electrical communication with the servo motor and a sensor associated with the hydraulic cylinder for automated operation.
