FAQ:

1. Q: How to replace the seals of the 4WRZ10?
A: Order Rexroth’s original seal kits, disassemble the valve, remove old seals, clean seal grooves, and install new seals (ensure compatibility with hydraulic fluid).

2. Q: What is the cause of erratic flow control?
A: Air in the hydraulic system, fluctuating input signal, contaminated fluid, worn spool, or faulty position feedback sensor.

3. Q: How to bleed air from the 4WRZ10 valve?
A: Operate the valve at low pressure with the actuator extended/retracted fully, opening bleeder valves (if available) until a steady fluid flow (without bubbles) is observed.

4. Q: Why is the valve overheating?
A: Excessive pressure drop, blocked drain port, insufficient fluid flow, or a faulty solenoid drawing excess current.

5. Q: How to test the position feedback sensor?
A: Measure the feedback signal (e.g., 4-20 mA) while shifting the spool manually; the signal should change proportionally to spool travel. No change indicates a faulty sensor.
