Typical application codes and recurring configurations
When selecting or replacing hydraulic valves for industrial systems, codes such as DHI-0713 23, DHI-0631/2/P and DHI-0711 are frequently searched (often entered as DHI071323, DHI0631/2/P and DHI0711), although they refer to the DHI series, which has been discontinued since 2022 and replaced by the DHE and DHL series. The same applies to the code SP-COU-24DC/80, sometimes searched as SPCOU24DC80 or SP COU 24DC 80, which identifies an electrically actuated 24 V DC on/off cartridge valve belonging to an Atos series that is no longer in production and used on existing industrial hydraulic systems. Other frequently searched Atos codes include DHA-0713, AGAM-10/10/210, AGAM-20/10/210 and DLHZO-TE-040 (also often entered as DHA0713, AGAM1010210, AGAM2010210 and DLHZOTE040). These codes refer to Atos hydraulic valves used for directional, pressure and flow control in industrial hydraulic systems.
