1. A hydraulic valve assembly, comprising:
a connection section;
a first valve section; and
a pressure line,
wherein the first valve section can be pressurized by the connection section via the pressure line,
wherein the first valve section comprises a first spool piston, a first spool diverter, at least one first consumer port of the first valve section, and at least one second consumer port of the first valve section,
wherein a first group of hydraulic consumers can be controlled via the at least one first consumer port of the first valve section,
wherein a second group of hydraulic consumers can be controlled via the at least one second consumer port of the first valve section, wherein the first spool diverter can be switched at least into a first spool diverter switching position and a second spool diverter switching position,
so that the first group of hydraulic consumers can be controlled via the first spool piston when the first spool diverter is in the first spool diverter switching position, and
so that the second group of hydraulic consumers can be controlled via the first spool when the first spool diverter is in the second spool diverter switching position, and
wherein a shut-off valve is disposed in the pressure line, and the shut-off valve blocks the pressure line in a blocking position,
wherein the shut-off valve can be switched from the blocking position into a first release switching position and a second release switching position, the pressure line being released in the first release switching position and in the second release switching position,
wherein the shut-off valve switches to the first release switching position when the first spool diverter is in the first spool diverter switching position allowing a pilot pressure to be applied to the shut-off valve, and
wherein the shut-off valve switches to the second release switching position when the first spool diverter is in the second spool diverter switching position allowing a pilot pressure to be applied to the shut-off valve.
