DHE-0631/2 DC 20 Solenoid Directional Valve

The ATOS DHE-0631/2 DC 20 solenoid directional valve is a direct-operated spool type hydraulic directional valve for on-off flow control in industrial hydraulic systems. Atos official product data identifies the DHE family as direct, spool type, subplate directional valves with AC or DC solenoids. For accurate purchasing and replacement, the complete model should be kept visible as DHE-0631/2 DC 20.

According to Atos official E015 technical data, DHE valves are spool type, two or three position, direct-operated solenoid directional valves with high performance threaded solenoids. The DHE series uses a subplate mounting interface and is designed for hydraulic circuits where oil flow must be switched between ports to control actuator movement, stop/start functions, unloading, clamping, lifting or other directional control operations.

The complete model code DHE-0631/2 DC 20 contains important configuration details. The DHE section identifies the Atos direct-operated high flow solenoid directional valve family. The 06 section identifies size 06 construction. The 63 configuration identifies a single solenoid valve with 2 external positions and spring offset. The 1/2 section identifies the spool type. The DC reference indicates DC solenoid execution, and the 20 suffix identifies the series or execution reference shown on the customer model.

Atos official DHE product information lists the valve as a direct, spool type, subplate valve available with AC or DC solenoids and connector options including DIN, AMP, Deutsch and wire connectors. The E015 technical table lists the DHE series with ISO 4401 size 06 mounting surface, 80 l/min maximum flow and 350 bar maximum pressure. These values should be checked against the final hydraulic schematic, circuit pressure, flow demand and machine documentation before replacement.

The DHE solenoid construction is designed for serviceability. Atos technical data states that the solenoids use wet type screwed tubes, different for AC and DC power supply, with integrated manual override pin. The coils are interchangeable and specific for AC or DC power supply. Standard coil protection is listed as IP65 when the correct connectors are assembled, with optional coil connector versions available for higher protection configurations.

In operation, the ATOS DHE-0631/2 DC 20 directional valve changes the hydraulic flow path when the solenoid is energized. The spool shifts inside the valve body and opens or closes the required port connections according to the 1/2 spool function. When the solenoid is de-energized, the spring offset design returns the valve to its rest position. This makes the valve suitable for electrically controlled hydraulic switching rather than proportional flow control.

The DHE valve body is designed for industrial hydraulic service. Atos data describes the valve body as a 3-chamber type made by shell-moulding casting with wide internal passages. This supports high flow performance for size 06 direct-operated directional valves. The recommended hydraulic fluid compatibility includes mineral oils according to DIN 51524, and seal options include NBR, FKM and HNBR depending on the ordered valve version.

The DHE-0631/2 DC 20 solenoid directional valve is commonly used in hydraulic power units, machine tools, presses, marine systems, clamping circuits, lifting systems, industrial automation equipment and general hydraulic machines requiring reliable on-off directional control. Because this valve controls hydraulic actuator movement, replacement should be based on the exact model code and hydraulic schematic, not only on appearance.

For procurement teams and maintenance engineers, short descriptions such as “DHE valve,” “Atos solenoid valve” or “DHE-0631 valve” are not enough for accurate replacement. Similar Atos DHE valves may differ in configuration, spool type, solenoid voltage, connector option, seal material, manual override version or series reference. The full model DHE-0631/2 DC 20 should remain visible in the product title, product description, quotation and purchase order.

Before purchasing the ATOS DHE-0631/2 DC 20 solenoid directional valve, users should compare the existing valve nameplate, coil voltage marking, hydraulic schematic, mounting interface and connector type. If the valve is installed on a machine, photos of the model marking, coil label, connector side and valve stack can help confirm whether this exact DHE version is required.
