Frequently Asked Questions
Q: Does the 4WRZ10 require a bypass valve for startup?
A: A bypass valve is not mandatory but recommended to flush the system before commissioning, removing contaminants that may damage the valve.
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.
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
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.
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.
