FAQ:

1. What is the correct order to connect hydraulic lines?
Connect pressure port (P) first, then return port (T), followed by working ports (A/B); bleed air from lines before energizing the valve .

2. How to test the spool position indicator?
Apply a gradual electrical input signal; the indicator should switch outputs when preset spool positions are exceeded (within the overlap range) .

3. What tools are required for 4WRZ installation?
Torque wrench (for mounting bolts), cable crimping tools (for electrical connections), and alignment pins (for subplate mounting) .

4. Operation & Control

4. How does the proportional control work on 4WRZ valves?
The electric input signal (e.g., 0-10 V) activates the proportional solenoid, which moves the pilot spool; pilot oil pressure then displaces the main spool proportionally to the input signal .

5. What input signal types are compatible with 4WRZ valves?
Analog signals (e.g., ±10 V) are standard; some variants with integrated electronics (OBE) may support digital signals .
