FAQ:

1. What is the recommended fluid cleanliness level for 4WREE valves?
Maintain fluid cleanliness to ISO 4406 Class 18/16/13 (or better) to prevent clogging of internal components and extend valve life.

2. How to replace the solenoid coil of a 4WREE valve?
Disconnect power, remove the coil’s mounting screws, pull the coil from the valve body, and install the replacement coil (ensuring compatibility with voltage and wiring). Torque screws to 2-3 Nm.

3. When should the valve’s seal rings be replaced?
Replace seal rings every 2 years (or 5000 operating hours), or immediately if leakage is detected. Use only Rexroth-approved replacement seals to avoid compatibility issues.

4. Can 4WREE valves be repaired or must they be replaced?
Minor issues (e.g., worn seals, faulty solenoids) can be repaired, but internal spool or housing damage typically requires valve replacement. Contact Rexroth service for complex repairs.
