FAQ:

1. Q: What should be done if the valve is noisy during operation?
A: Check for cavitation (low inlet pressure), loose mounting, air in the system, or worn internal components; address the root cause (e.g., increase inlet pressure, bleed air).

2. Q: How to prevent contamination of the 4WRZ10?
A: Use high-quality hydraulic fluid, install proper filters (10 μm), regularly replace filters, and keep the system clean during maintenance.

3. Q: Can worn spools be repaired, or must they be replaced?
A: Minor wear can be polished (if within tolerance), but significant wear (e.g., scoring, excessive clearance) requires spool replacement with genuine Rexroth parts.

4. Q: Why does the valve drift from its set position?
A: Drift may result from unstable input signals, temperature changes, worn springs, or a faulty position feedback system; calibrate the valve and check the controller.

5. Q: How to check for internal leakage in the 4WRZ10?
A: Measure the flow rate from the T port when the valve is in neutral position; excessive flow (beyond Rexroth’s specifications) indicates internal leakage.
