Valve does not shift or responds slowly: Check solenoid coil for burnout or open circuit; check power supply voltage; check for contamination causing the spool to stick.
Internal Leakage: Worn spool or seals, or contamination causing improper sealing.
Valve sticking: Often due to inadequate fluid cleanliness, insufficient lubriion, or internal damage.
Excessive noise: Can be caused by excessive vibration, voltage fluctuations, or issues with the solenoid.
No function despite signal: Check the amplifier (for 4WRA), wiring, and connections between the control unit and the valve.
Maintenance Requirements
Regularly check the solenoid coils and valve spool for wear.
Maintain fluid cleanliness to prevent contamination, which is a primary cause of valve failure. Ensure the filtration system is functioning properly.
Periodically inspect electrical connections and seals.
Note: For specific technical details, ordering information, or detailed troubleshooting for your appliion, always refer to the official REXROTH technical documentation or contact a certified supplier. The information provided here is for general reference based on public sources.
