3. Installation Instructions
3.1 Pre-Installation
- Ensure the air supply is immaculate, devoid of moisture, oil, or any contaminants for optimal performance.
- Verify the valve model compatibility with the machine's pneumatic interfaces to guarantee seamless integration.
3.2 Installation Procedure
1. Mounting: Securely affix the valve in a vertical orientation at its assigned location on the press pneumatic control panel using robust M6 bolts for reliable anchoring.
2. Pneumatic Connections:
- Main Circuit: Connect the air supply to the inlet (P) and ensure seamless linkage of the actuator (e.g., cylinder) to the outlet (A).
- Redundant Circuit: Integrate the independent backup channel to eliminate any risk of cross-interference.
3. Electrical Wiring:
- Solenoid Coil Voltage Options: Compatible with DC24V±10% or 110V/220V; specify in advance. Ensure proper polarity with red as positive and black as negative to achieve a flawless setup.
- For maximum safety, ground the wire to the equipment's earthing terminal securely.
4. Operating Procedures
4.1 Pre-Operation Checks
- Verify that the manual reset button is toggled to the "ON" position, readying the system for operation commencement.
- Engage the test button to simulate an emergency stop, ensuring flawless dual-channel coordination.
4.2 Normal Operation
- Throughout standard operations, both valves operate in perfect sync. Should a channel fail, a red alert light activates, and the backup system seamlessly takes over, maintaining uninterrupted performance.
4.3 Emergency Stop
- Engage the E-stop button to immediately halt the air supply, ensuring the press slide ceases movement instantly for unparalleled safety.

5. Maintenance
5.1 Routine Maintenance
- Execute weekly cleaning of the valve surface and perform a thorough inspection of air hose connections to detect any potential leaks.
- Conduct a monthly evaluation of the response time; diligently record results to ensure precise maintenance.
5.2 Periodic Service
- For optimal longevity of your machinery, replace seals biannually and cleanse the spool meticulously using anhydrous ethanol.
- Elevate your machinery's peak performance by ensuring professional calibration of solenoids and sensors on an annual basis.
6. Troubleshooting
Symptom | Possible Cause | Solution
Valve Inaction: If the valve is inactive due to power off or coil burnout, verify the wiring immediately and replace the coil if necessary to restore seamless operation.
Air Leakage: Facing issues with seal degradation or loose fittings? Secure peace of mind by promptly replacing seals or tightening fittings.
Delayed Response: If experiencing low pressure or spool blockage, enhance performance by increasing pressure or thoroughly cleaning the spool for swift operation.
7. Safety Warnings
- 1. NEVER disassemble the valve while under pressure! Always ensure the system is fully depressurized before servicing to guarantee utmost safety.
- 2. Internal adjustments are strictly prohibited for non-authorized personnel to maintain system integrity and ensure safety.
- 3. Immediately shutdown operations if any abnormal noise or leakage is detected to prevent potential damage or hazards.
