FAQ;
What are common troubleshooting issues?
Common problems and their potential causes include :
• Valve does not shift or responds slowly: Check solenoid coil for burnout or open circuit; check power supply voltage; check for contamination causing the spool to stick.
• Internal Leakage: Worn spool or seals, or contamination causing improper sealing .
• Valve sticking: Often due to inadequate fluid cleanliness, insufficient lubrication, or internal damage .
• Excessive noise: Can be caused by excessive vibration, voltage fluctuations, or issues with the solenoid .
• No function despite signal: Check the amplifier (for 4WRA), wiring, and connections between the control unit and the valve .
8. What maintenance is required?
• Regularly check the solenoid coils and valve spool for wear .
• Maintain fluid cleanliness to prevent contamination, which is a primary cause of valve failure. Ensure the filtration system is functioning properly .
• Periodically inspect electrical connections and seals.
