3. Installation Instructions
3.1 Pre-Installation
- Ensure the air supply is immaculate, free from moisture, oil, or any contaminants that could jeopardize performance.
- Verify that the valve model is perfectly compatible with the machine's pneumatic interfaces, ensuring smooth integration.
3.2 Installation Procedure
1. Mounting: Position the valve securely and vertically on the designated section of the pneumatic control panel using robust M6 bolts to ensure steadfast stability.
2. Pneumatic Connections:
- Main Circuit: Connect the air supply to the inlet (P) and ensure flawless connection of the actuator (e.g., cylinder) to the outlet (A).
- Redundant Circuit: Install the backup channel independently to avert any cross-interference, bolstering reliability.
3. Electrical Wiring:
- Solenoid Coil Voltage: Choose from DC24V±10% or 110V/220V. Ensure the red wire is positive and black is negative, creating an impeccable and safe setup.
- Ground the wire securely to the equipment's earthing terminal, enhancing safety and preventing electrical mishaps.
4. Operating Procedures
4.1 Pre-Operation Checks
- Toggle the manual reset button to the "ON" position to initiate operations smoothly.
- Activate the test button to simulate an emergency stop, confirming the impeccable coordination of dual channels.
4.2 Normal Operation
- In routine operations, both valves work in unison. A channel failure activates a red alert light and automatically engages the backup system, maintaining seamless and uninterrupted performance.
4.3 Emergency Stop
- Engage the E-stop button to instantly cut off the air supply, bringing the press slide to an immediate halt and ensuring unmatched safety.

5. Maintenance
5.1 Routine Maintenance
- Weekly cleaning of the valve surface and thorough inspection of air hose connections are vital to detect and prevent leaks.
- Monthly evaluation of response time is crucial; diligently record this data for accurate and precise maintenance.
5.2 Periodic Service
- Replace seals every six months and cleanse the spool using anhydrous ethanol to ensure the valve's optimal longevity and performance.
- Ensure annual professional calibration of solenoids and sensors to maintain peak performance and extend the life of your machinery.
6. Troubleshooting
Symptom | Possible Cause | Solution
Valve Inaction: Experience power issues or coil burnout? Easily verify and correct wiring or replace the coil to ensure seamless operation and efficiency.
Air Leakage: Facing seal degradation or loose fittings? Secure your system's reliability by promptly replacing seals or tightening fittings for optimal performance.
Delayed Response: Notice low pressure or spool blockage? Elevate your machinery's performance by increasing pressure or thoroughly cleaning the spool for swift, efficient operation.
7. Safety Warnings
- 1. NEVER attempt to disassemble the valve while under pressure! Always ensure the entire system is fully depressurized before servicing to guarantee utmost safety.
- 2. Internal adjustments should only be performed by authorized personnel to preserve system integrity and ensure safety.
- 3. Immediately cease operations if any abnormal noise or leakage is detected to prevent potential damage or serious hazards.
