FAQ:

1. Q: How to verify the electrical wiring of the 4WRZ10?
A: Check for correct polarity (solenoid +/-, feedback signals), continuity, and insulation resistance (> 1 MΩ) using a multimeter; refer to the wiring diagram in the manual.

2. Q: What is the maximum allowable backpressure at the T port?
A: The maximum backpressure at the tank port (T) is 10 bar (145 psi); excess backpressure can affect flow regulation and valve performance.

Operation & Control

3. Q: How does the proportional control work in the 4WRZ10?
A: The input electrical signal (4-20 mA/0-10 V) controls the proportional solenoid, which shifts the spool proportionally to adjust the flow rate through ports A/B; position feedback maintains accuracy.

4. 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.

5. 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).
