    摘要： A hydraulic valve assembly includes a connection section, a first valve section and a pressure line. The first valve section has a first spool piston, a first spool diverter, at least one first consumer port and at least one second consumer port. The first spool diverter can be switched at least into a first spool diverter switching position and a second spool diverter switching position. A shut-off valve is disposed in the pressure line and blocks the pressure line in a blocking position and can be switched from the blocking position into a first release switching position and a second release switching position. The shut-off valve switches into the first release switching position when the first spool diverter is in the first spool diverter switching position and into the second release switching position when the first spool diverter is in the second spool diverter switching position.

    摘要： A power unit with manual override control for a hydraulic system having an initial state and at least one operational state is provided, comprising: a tank for storing hydraulic fluid that moves between a first chamber and a second chamber of a hydraulic cylinder; a pump that routes the hydraulic fluid in and out of the tank; a first relief valve; a first solenoid valve configured to shift between a plurality of positions based on the at least one operational state of the hydraulic system; a first check valve connected to the first solenoid valve; a manual override control unit comprising: a second check valve; and a second solenoid valve configured to shift between a plurality of positions based on activation of a manual override control, wherein the activation of the manual override control returns the hydraulic system from the at least one operational state to the initial state.
