FAQ:

1. How to adjust the flow rate of a 4WRZ valve?
Modify the electrical input signal amplitude; flow rate increases proportionally with signal strength (within the valve’s maximum flow rating) .

2. What happens if the electrical input signal is interrupted?
The solenoids de-energize, and centering springs return the main spool to the central position, stopping flow to working ports .

3. How to reverse flow direction with a 4WRZ valve?
Activate the opposite proportional solenoid (e.g., solenoid "A" for P→A/B→T, solenoid "B" for P→B/A→T) .

4. Can 4WRZ valves be operated manually in an emergency?
Yes, use the optional manual override to move the control spool, but ensure machine safety protocols are followed .

5. What is the response time of 4WRZ valves?
Response time varies by size and input signal, but typical 0→100% switching time ranges from 50-200 ms (pilot-controlled) .
