3. Installation Instructions
3.1 Pre-Installation
- Prioritize cleanliness: Ensure your air supply is clean, dry, and devoid of any oil or contaminants.
- Confirm the valve model is compatible with the machine's pneumatic interfaces for a seamless fit.
3.2 Installation Procedure
1. Mounting: Securely affix the valve vertically in its designated position on the pneumatic control panel using M6 bolts, ensuring stability and precision.
2. Pneumatic Connections:
- Main Circuit: Establish a connection from the air supply to inlet (P) and direct the actuator (like a cylinder) to outlet (A) for smooth functionality.
- Redundant Circuit: Ensure independent connections for the backup channel, avoiding any cross-interference.
3. Electrical Wiring:
- Solenoid Coil Voltage: Ensure stable operation with DC24V±10% or 110V/220V (specify beforehand) (Red: +, Black: -).
- Securely ground the wire to the equipment's earthing terminal for enhanced safety.
4. Operating Procedures
4.1 Pre-Operation Checks
- Verify the manual reset button is in the "ON" position to commence operations accurately.
- Engage the test button to simulate an emergency stop and confirm dual-channel synchronization for fail-safe operations.
4.2 Normal Operation
- In operation, both valves function harmoniously. Should any channel fail, the red alarm light activates, triggering an automatic backup for uninterrupted safety.
4.3 Emergency Stop
- Press the E-stop button to promptly cut off the air supply, bringing the press slide to an immediate halt with precision.

5. Maintenance
5.1 Routine Maintenance
- Weekly, maintain the valve's pristine condition by cleaning its surface and inspecting air hose connections for leaks.
- Conduct monthly response time tests and meticulously record the data to ensure optimal performance.
5.2 Periodic Service
- Biannually replace seals and use anhydrous ethanol for cleaning the spool to maintain its efficiency.
- Annually, engage in professional calibration of solenoids and sensors to uphold precision and reliability.
6. Troubleshooting
Symptom Possible Cause Solution
Valve Inaction Power off / Coil burnout Thoroughly check the wiring connections; replace the coil if necessary for restoration.
Air Leakage Issue: Experiencing seal degradation or loose fittings? Ensure peak performance by replacing seals or tightening fittings for uninterrupted operation.
Delayed Response Dilemma: Faced with low pressure or spool blockage? Elevate your system's efficiency by increasing pressure or cleaning the spool for flawless functionality.
7. Safety Warnings
- 1. NEVER attempt to disassemble the valve while it is under pressure. Always ensure the system is depressurized before proceeding with any service to maintain safety.
- 2. Avoid internal adjustments by unauthorized personnel to preserve system integrity and safety.
- 3. Initiate an immediate shutdown if any abnormal noise or leakage is detected to prevent potential hazards and ensure safety.
