FAQ:

1. Q: How to connect the hydraulic ports of the 4WRZ10?
A: Standard port labeling follows ISO 4401: P (pressure inlet), T (tank return), A/B (work ports to actuators); refer to the valve’s nameplate or datasheet for specific port configurations.

2. Q: What type of electrical connector is used for the 4WRZ10?
A: Common connectors include DIN 43650 (solenoid side) and M12x1 (feedback signal), with IP65 or higher protection class for harsh environments.

3. Q: Is a separate power supply required for the proportional solenoid?
A: Yes, the solenoid requires a stable DC power supply (typically 24 V DC ±10%); use a regulated power supply to avoid signal fluctuations.

4. 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.

5. 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.
