Hydraulic section (1) including: a main spool (2);a pressure compensator (40;4) able to maintain a substantially constant pressure drop through a metering orifice (3) of the main spool (2); a first chamber (7) interposed between the main spool (2) and a first end (16a) of the compensator (40;4) and a second chamber (6) situated at a second end (16b) of the compensator (40;4), the second chamber (6) being connectable to a feed line (Pal) from a pump (100) by a predefined channel (Pp) in such a way that said hydraulic section (1) operates as a priority section, and being connectable to a line (LS) for detecting the highest load pressure in such a way that the hydraulic section (1) operates as a flow-sharing section.
