Abstract
Path valve disk has a cast housing with a design that accommodates the disk itself which is also a mass produced cast part. The valve housing accommodates the valve disk, which operates on the load sensing principle. The design has a new sand core for use in the casting process to accommodate the valve disk. In a second valve bore of a regulating piston a pressure scale is incorporated.
