ABSTRACT:
A valve stack for a work machine is disclosed. The valve stack has first and second valve bodies, each with first and second mounting surfaces and first and second valve members. The valve stack further has a third valve body with a mounting surface configured to engage the second mounting surfaces of the first and second valve bodies, and at least one valve member disposed within the third valve body. The at least one valve member is movable between a first position at which movement of a first operator control device corresponds to movement of the first valve member and movement of a second operator control device corresponds to movement of the second valve member, and a second position at which movement of the first operator control device corresponds to movement of the second valve member and movement of the second operator control device corresponds to movement of the first valve member.
