FAQ;

5. How do I install the 4WE6 Series Valve correctly? Follow these steps to ensure safe and efficient installation: 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? Regular maintenance extends the valve’s lifespan and prevents system failures. Key tasks include: • 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).
