3. Installation Instructions
3.1 Pre-Installation
- Ensure the air supply is impeccably clean, dry, and devoid of oil or contaminants.
- Verify that the valve model is compatible with the machine's pneumatic interfaces.
3.2 Installation Procedure
1. Mounting: Securely install the valve vertically in its designated position on the press pneumatic control panel with M6 bolts.
2. Pneumatic Connections:
- Main Circuit: Connect the air supply to the inlet (P) and the actuator (e.g., cylinder) to the outlet (A).
- Redundant Circuit: Connect the backup channel independently to avoid cross-interference.
3. Electrical Wiring:
- Solenoid Coil Voltage: Choose DC24V±10% or 110V/220V (specify in advance) (Red: +, Black: -).
- Ensure reliable grounding by connecting the wire to the equipment earthing terminal.
4. Operating Procedures
4.1 Pre-Operation Checks
- Verify that the manual reset button is set to the "ON" position.
- Engage the test button to simulate an emergency stop and confirm dual-channel synchronization.
4.2 Normal Operation
- During standard operation, both valves function in unison. If either channel fails, a red alarm light activates, triggering automatic backup.
4.3 Emergency Stop
- Press the E-stop button to synchronously halt the air supply, immediately stopping the press slide.

5. Maintenance
5.1 Routine Maintenance
- Weekly: Clean the valve surface and inspect air hose connections for leaks.
- Monthly: Test response time and meticulously record all data.
5.2 Periodic Service
- Every 6 months: Replace seals and clean spool using anhydrous ethanol for optimal performance.
- Annually: Perform professional calibration of solenoids and sensors.
6. Troubleshooting
Symptom Possible Cause Solution
Valve Inaction Power off / Coil burnout Check wiring carefully; replace coil promptly if needed.
Air Leakage Problem: Seal degradation or loose fittings. Solution: Replace seals or tighten fittings to restore optimal function.
Delayed Response Problem: Low pressure or spool blockage. Solution: Increase pressure or clean the spool for faster response time.
7. Safety Warnings
- 1. NEVER attempt to disassemble the valve while it is under pressure! Ensure you depressurize the system completely before conducting any servicing.
- 2. Only authorized personnel may perform internal adjustments; unauthorized adjustments are strictly prohibited.
- 3. Immediately shut down operations if any abnormal noise or leakage is detected to prevent further damage.
