Frequently Asked Questions
What are the key features of the 4WRA6 valve?
  • Direct-operated design for precise flow control without external feedback
  • Proportional solenoid control with detachable coils and centering thread for easy maintenance
  • Spring-centered spool that returns to neutral when de-energized
  • Compatibility with external electronics (e.g., Eurocard amplifiers) for signal control
  • Compact sizes: NG6 and NG10
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.

Where is the 4WRA6 typically used?

This valve suits appliions 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
How do I select the right model?

Model codes indie specifiions (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.

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
