FAQ:
1.Why does the valve produce excessive noise?
Noise can stem from cavitation (low fluid pressure), loose mounting bolts, or air in the hydraulic system. Bleed the system, check for leaks, and ensure the supply pressure is within the recommended range.
Maintenance & Service
2. How often should 4WREE valves be inspected?
Routine inspections are recommended every 6 months (or 1000 operating hours), including checks for leakage, wiring damage, and fluid contamination.
3. 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.
4. 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.
5. 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.
6. 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.
