FAQ:

1. Q: Can the 4WRZ10 be used for pressure control?
A: While primarily a directional/flow control valve, some models integrate pressure relief functions or can be paired with pressure compensators for pressure regulation.

2. Q: What is the difference between the 4WRZ10 and 4WRZE10 series?
A: The 4WRZE10 adds an integrated electronic amplifier, while the 4WRZ10 requires an external amplifier for proportional control.

3. Q: How to achieve closed-loop control with the 4WRZ10?
A: Connect the spool position feedback signal to a controller (e.g., PLC, motion controller), which adjusts the input signal based on the desired vs. actual position.

4. Q: What is the maximum frequency response of the 4WRZ10?
A: The typical frequency response is ≥ 10 Hz (±3 dB), suitable for dynamic motion control applications.

5. Q: Can the 4WRZ10 handle bi-directional flow?
A: Yes, the 4-way spool design allows flow in both directions (A to B and B to A) based on the input signal.
