FAQ:

1. Q: How to calibrate the spool position feedback of the 4WRZ10?
A: Use the manufacturer’s calibration software (e.g., Rexroth IndraWorks) or external tools to adjust the zero point and full-scale output, ensuring alignment between the electrical signal and spool travel.

2. Q: What is the recommended filter fineness for the hydraulic system with 4WRZ10?
A: A minimum filter fineness of 10 μm (β10 ≥ 75) is required to protect the valve’s precision components from contamination.

3. Q: Can the 4WRZ10 be mounted in a manifold?
A: Yes, it is compatible with manifold mounting (ISO 4401 manifolds) for space-saving and centralized hydraulic system designs.

4. Q: How to prevent leakage at the hydraulic connections?
A: Use O-rings or flat gaskets (compatible with hydraulic fluid) and ensure proper port cleaning before assembly; avoid over-tightening bolts.

5. Q: What is the correct way to connect the drain port (if applicable)?
A: The drain port (marked “R” or “L”) should be connected to the tank with minimal backpressure (< 3 bar) to ensure proper solenoid cooling and seal lubrication.
