Key Specifications
- Maximum Operating Pressure: Up to 350 bar for P, A, B ports
- Maximum Flow: Varies with model (e.g., 42 L/min for some 4WRAE6 models)
- Recommended Fluid Cleanliness: ISO 4406 20/18/15
- Voltage: Typically 24 V DC
Common Applications
- Plastic injection molding machines
- Presses and bending machines
- Mobile equipment
- Industrial automation systems requiring proportional control
Troubleshooting
- Valve does not shift or responds slowly: Check solenoid coil, power supply voltage, and contamination
- Internal Leakage: Worn spool or seals, or contamination
- Valve sticking: Inadequate fluid cleanliness or insufficient lubrication
- Excessive noise: Vibration, voltage fluctuations, or solenoid issues
- No function despite signal: Check amplifier, wiring, and connections
Maintenance Requirements
- Regularly check solenoid coils and valve spool for wear
- Maintain fluid cleanliness and proper filtration
- Periodically inspect electrical connections and seals
