Zusammenfassung:	An assembly of a plurality of hydraulic control valves is housed in a single-piece body. For each control valve, a spool bore and an aperture for a pressure compensation valve are provided in the monolithic body. Each spool bore is connected to several return passages and a supply passage that extend through the monolithic body. A pair of workports also is connected to each spool bore. A relief valve return passage also extends through the monolithic body and where needed, apertures for pressure relief valves extend from a surface of the monolithic body intersecting the relief valve return passage and a given workport. A load sense passage and a second supply passage also are formed in the monolithic body.
