FAQ:

1. How to monitor valve performance during operation?
Use the spool position indicator outputs (if equipped) for superior control system monitoring; check for consistent flow proportional to input signals .

2. What is the maximum duty cycle for 4WRZ solenoids?
Solenoids are rated for continuous duty (100% duty cycle) within specified voltage and temperature ranges .

3. How to prevent uncontrolled movements when using the manual override?
Ensure the machine is in a safe state (e.g., lowered load, isolated power) before activating the override; follow lockout-tagout procedures .

4. Can 4WRZ valves be used in closed-loop control systems?
Yes, when paired with external position or pressure sensors to provide feedback to the control system .

5. What is the effect of fluid temperature on valve operation?
Optimal fluid temperature is -20 to +80 °C; temperatures outside this range may reduce response time or damage seals .
