FAQ;
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). 7. What are common issues with the 4WE6 Series, and how to troubleshoot them? Below are frequent problems, causes, and solutions: Symptom Possible Cause Troubleshooting Solution Valve fails to actuate (no movement) 1. No power to solenoid
2. Faulty solenoid
3. Spool seized 1. Check wiring/fuse; test voltage with a multimeter
2. Replace solenoid coil
3. Flush valve; replace contaminated fluid Leaks at ports/connections 1. Loose bolts
2. Damaged O-rings/seals
3. Thread misalignment 1. Retorque bolts to specs
2. Replace seals (use OEM parts)
3. Realign ports; replace damaged threads Spool sticks or moves sluggishly 1. Fluid contamination
2. Low fluid viscosity
3. Worn spool 1. Flush system; replace filter
2. Use fluid with correct viscosity (ISO VG 32–46)
3. Replace spool or valve cartridge Solenoid overheats 1. Incorrect voltage (e.g., 12V coil on 24V supply)
2. EMI interference 1. Verify voltage match; replace coil if burned
2. Install EMI filter; use shielded cables 8. Can the 4WE6 Series be used with water-glycol or other non-mineral fluids? Most standard 4WE6 Series valves are designed for mineral oil-based fluids. However, specialized models (with compatible seals and materials) can handle water-glycol (common in mobile equipment) or fire-resistant fluids. • Critical Check: Confirm the valve’s seal material (e.g., Viton or EPDM) is compatible with your fluid—nitrile seals (standard) degrade in water-glycol. • Consult Manufacturer: Always verify fluid compatibility with the supplier before use to avoid seal failure or spool damage.
