3. Installation Instructions
3.1 Pre-Installation
- Ensure the air supply is immaculate, devoid of moisture, oil, and contaminants for flawless performance.
- Verify that the valve model is perfectly compatible with the machine's pneumatic interfaces.
3.2 Installation Procedure
1. Mounting: Secure the valve vertically on the press pneumatic control panel using M6 bolts to ensure a robust installation.
2. Pneumatic Connections:
- Main Circuit: Seamlessly connect the air supply to the inlet (P) and the actuator (e.g., cylinder) to the outlet (A).
- Redundant Circuit: Independently set up the backup channel to avoid any cross-interference.
3. Electrical Wiring:
- Solenoid Coil Voltage: Compatible with DC24V±10% or 110V/220V; specify in advance. Ensure the red wire is positive and black is negative for a flawless setup.
- For utmost safety, securely ground the wire to the equipment's earthing terminal.
4. Operating Procedures
4.1 Pre-Operation Checks
- Make sure the manual reset button is set to "ON" to initiate operations.
- Engage the test button to simulate an emergency stop, ensuring the dual channels operate in perfect synchrony.
4.2 Normal Operation
- In standard operations, both valves perform in unison. Should a channel fail, a red alert light activates and the backup system automatically takes over, maintaining smooth operation.
4.3 Emergency Stop
- Use the E-stop button to instantly cut air supply, immediately stopping the press slide for superior safety.

5. Maintenance
5.1 Routine Maintenance
- Conduct a weekly cleaning of the valve surface and meticulously check air hose connections for any leaks.
- A monthly review of response time is crucial; diligently record data for precise maintenance.
5.2 Periodic Service
- Replace seals every six months and cleanse the spool with anhydrous ethanol to ensure lasting performance and durability.
- To maintain optimal performance, ensure professional calibration of solenoids and sensors is conducted annually. This guarantees peak functionality and precision.
6. Troubleshooting
Symptom | Possible Cause | Solution
Valve Inaction: Power off or coil burnout? Verify the wiring for any discrepancies; replace the coil if necessary to ensure flawless and seamless operation.
Air Leakage: Facing issues with seal degradation or loose fittings? Secure peace of mind by promptly replacing seals or tightening fittings to ensure a secure operation.
Delayed Response: Experiencing low pressure or spool blockage? Enhance system performance by increasing pressure or cleaning the spool to ensure swift, responsive operation.
