Common Applications
- Plastic injection molding machines
- Presses and bending machines
- Mobile equipment
- Industrial automation systems where proportional control of speed and direction is needed
Troubleshooting
- 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
Maintenance Requirements
- 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
