1. A switching valve block for a hydraulically actuatable work machine comprising:
a plurality of valve block inputs for a respective connection to a pressure output of one or more hydraulic fluid pumps;
a plurality of valve block outputs for outputting a pressurized hydraulic fluid; and
at least one valve arranged between valve block inputs and valve block outputs and adapted to selectively produce a fluid connection between a first valve block input and a first valve block output or between a first valve block input and a second valve block output, wherein
a first valve block output has a fixed fluid connection to a second valve block input, and
a second valve block output has a fixed fluid connection to a third valve block input.
