FAQ:
1. What causes leakage from the valve’s drain port?
Drain port leakage may result from excessive backpressure (exceeding 5 bar), worn seal rings, or internal spool damage. Ensure the drain line is unobstructed and check seal integrity.
2. Why is the valve’s flow rate inconsistent?
Inconsistent flow can be due to contaminated hydraulic fluid (clogging the valve’s orifices), fluctuating supply pressure, or a damaged proportional solenoid. Filter the fluid and inspect the solenoid for wear.
3. What if the valve overheats during operation?
Overheating may occur from high pressure drops (exceeding the valve’s rated ΔP), insufficient fluid flow through the valve, or a stuck spool. Reduce pressure drop and ensure adequate fluid circulation.
4. Why does the valve produce excessive noise?
Noise can stem from cavitation (low fluid pressure), loose mounting bolts, or air in the hydraulic system. Bleed the system, check for leaks, and ensure the supply pressure is within the recommended range.
Maintenance & Service
5. How often should 4WREE valves be inspected?
Routine inspections are recommended every 6 months (or 1000 operating hours), including checks for leakage, wiring damage, and fluid contamination.
