FAQ:

How does the 4WRA6 valve work?

When an electrical signal is sent to the proportional solenoid, it generates a force that moves the spool proportionally. This adjusts the opening of flow paths between ports P (pressure), A/B (actuator lines), and T (tank), enabling continuous control of flow direction and volume. The spool returns to center via springs when de-energized .

4. Where is the 4WRA6 typically used?

This valve suits applications requiring precise hydraulic control, such as:

• Industrial machinery (e.g., presses, plastic injection molding) .

• Mobile equipment (e.g., cranes, excavators) .

• Systems needing directional and flow control without integrated electronics .

5. How do I select the right model?

Model codes indicate specifications (e.g., 4WRA6E07-2X/G24N9K4/V):

• 4WRA6: Series and size (NG6).

• E07: Spool type and control configuration.

• G24N9K4: 24V DC supply, corrosion-resistant coating .

Consult REXROTH datasheets or suppliers for exact requirements like flow rate, spool type, and electrical inputs .

6. What are critical installation notes?

• Use the specified subplate (ISO 4401) to avoid leakage .

• Ensure the tank line is never unloaded; a pre-load valve (~2 bar) may be required .

• Verify electrical connections (e.g., 24V DC) and coil compatibility .

7. How is maintenance handled?

• Regularly check for spool sticking or contamination.

• Clean filters and monitor hydraulic fluid quality.

• Replace coils or seals if movement is sluggish .
