FAQ;

5. How do I install the 4WE6 Series Valve correctly?

1. Pre-Installation Check:
   • Verify the valve model matches your system’s pressure/flow requirements.
   • Inspect for damage (e.g., cracked housing, bent pins) and clean ports to remove debris.
2. Mounting:
   • Use a compatible subplate/manifold (align bolt holes with ISO 4413 standards).
   • Torque mounting bolts to the manufacturer’s specifications (typically 15–25 N·m) to avoid leaks.
3. Fluid Connection:
   • Connect ports per the valve’s schematic (P = supply, T = return, A/B = to actuator).
   • Use thread sealant (e.g., PTFE tape) on pipe threads (avoid over-applying to prevent clogging).
4. Electrical Wiring:
   • Match solenoid voltage to the power supply (e.g., 24V DC).
   • Use shielded cables for AC solenoids to reduce electromagnetic interference (EMI).
   • Ground the valve body (if required) to prevent static buildup.

6. What maintenance is required for the 4WE6 Series?

• Fluid Quality Checks: Test hydraulic fluid for contamination (ISO 4406 cleanliness code ≤ 18/15) and replace filters every 6–12 months (or per system hours).
• Solenoid Inspection: Check wiring connections for corrosion or loose terminals; replace solenoids if they overheat ( > 60°C surface temperature) or fail to actuate.
• Leak Detection: Inspect port connections and spool seals quarterly. Replace O-rings/seals (typically nitrile or Viton) if leaks are detected.
• Manual Override Test: Activate the manual override (if equipped) monthly to ensure spool mobility (prevents seizing).
