FAQ
▔▔Q1: How do I confirm the exact model code for my replacement Atos valve?
A: Check the metal nameplate located on the side of the main valve body. Look for the complete ordering string (e.g., DHI-0631/2/A-X 24DC). If the tag is damaged, measure the interface mounting pattern dimensions (CETOP 3 or CETOP 5) and inspect the spool switching diagram printed on the tag.
Q2: What filtration level is recommended for long valve service life?
A: For standard direct-operated directional valves, a fluid cleanliness level according to ISO 4406 class 20/18/15 (using a filter rating of 25 microns) is recommended. For proportional or pilot-operated models with LVDT feedback, maintain ISO 4406 class 18/16/13 (using a 10-micron filter).
Q3: What hydraulic fluid types are compatible with Atos valves?
A: Mineral-based hydraulic oils (HLP/HM types according to DIN 51524) are standard. For water-glycol or synthetic fire-resistant fluids, specify valves fitted with Viton (FKM) seals by adding the appropriate option code.

FAQ
▔▔Q1: What does the code "DKE-1713" specifically indicate in Atos nomenclature?
A: "DKE" signifies a direct-acting, size 10 directional control valve. The first digit after the dash represents the series, "7" designates a double solenoid configuration, and "13" defines the specific 3-position, spring-centered spool hydraulic schematic (such as motor spool or standard configurations).
Q2: Are the electrical coils on the DKE-1713 interchangeable between AC and DC versions?
A: No. While coils are fully interchangeable within the same power supply type (e.g., swapping one DC coil for another DC coil without tools), AC and DC solenoids utilize distinct internal tube assemblies and are specific to their power supply category.
