3. Installation Instructions
3.1 Pre-Installation
- Ensure air supply is clean, dry, and free from oil/contaminants.
- Verify valve model matches machine pneumatic interfaces.
3.2 Installation Procedure
1. Mounting: Securely install valve vertically in designated position on press pneumatic control panel using M6 bolts.
2. Pneumatic Connections:
- Main Circuit: Connect air supply to inlet (P) and actuator (e.g., cylinder) to outlet (A).
- Redundant Circuit: Independently connect backup channel without cross-interference.
3. Electrical Wiring:
- Solenoid Coil Voltage: DC24V±10% or 110V/220V (specify in advance) (Red: +, Black: -).
- Reliably ground wire to equipment earthing terminal.
4. Operating Procedures
4.1 Pre-Operation Checks
- Confirm manual reset button is in "ON" position.
- Activate test button to simulate emergency stop and validate dual-channel synchronization.
4.2 Normal Operation
- During operation, both valves work simultaneously. Failure of either channel triggers red alarm light and automatic backup activation.
4.3 Emergency Stop
- Press E-stop button to synchronously cut off air supply, halting press slide immediately.

5. Maintenance
5.1 Routine Maintenance
- Clean valve surface weekly; inspect air hose connections for leaks.
- Monthly test response time and record data.
5.2 Periodic Service
- Replace seals every 6 months; clean spool with anhydrous ethanol.
- Annual professional calibration of solenoids and sensors.
6. Troubleshooting
Symptom Possible Cause Solution
Valve Inaction: If you encounter power-off situations or coil burnout, it's time for immediate action. Ensure the wiring is correct, and if necessary, replace the coil to restore optimal functionality.
Air Leakage: Detecting seal degradation or dealing with loose fittings? Enhance the performance by replacing seals or tightening fittings to secure airtight integrity.
Delayed Response: Experience low pressure or spool blockage? Act now by increasing pressure or cleaning the spool to ensure swift and efficient valve response.
7. Safety Warnings
- 1. NEVER attempt to disassemble the valve while it's under pressure! Always depressurize to ensure a safe environment before proceeding with any servicing.
- 2. Internal adjustments are strictly forbidden for non-authorized personnel. Ensure only qualified experts handle such modifications.
- 3. If you notice any abnormal noise or unexpected leakage, immediately shut down the system to prevent potential risks.
