FAQ:

0. Q: Can the 4WRZ10 be operated manually in case of electrical failure?
A: Yes, most models feature a manual override (mechanical lever or hex key) to shift the spool manually for emergency operation.

1. Q: What is the neutral position function of the 4WRZ10’s 4/3 spool?
A: Common neutral positions include: closed center (P, A, B blocked, T open), open center (P connected to T, A/B blocked), or tandem center (A connected to B, P connected to T).

2. Q: How to adjust the flow rate of the 4WRZ10?
A: Adjust the input electrical signal (increase/decrease current/voltage) or use the built-in flow adjustment screw (if equipped) for fine-tuning.

3. 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.

4. 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.

5. 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.
