3. Installation Instructions
3.1 Pre-Installation
- Ensure the air supply is immaculate, devoid of moisture, oil, and contaminants for peak performance.
- Validate the valve model's compatibility with your machine's pneumatic interfaces.
3.2 Installation Procedure
1. Mounting: Position the valve in an upright orientation on the designated pneumatic control panel of the press. Use M6 bolts to achieve a robust and secure installation.
2. Pneumatic Connections:
- Main Circuit: Connect the air supply to inlet (P) and link the actuator (e.g., cylinder) to outlet (A) for seamless functionality.
- Redundant Circuit: Independently connect the backup channel to avoid any interference, ensuring reliability.
3. Electrical Wiring:
- Solenoid Coil Voltage: Supports DC24V±10% or 110V/220V; specify the desired voltage in advance. Connect the red wire as positive and the black as negative for flawless operation.
- Properly ground the wire to the equipment's earthing terminal to guarantee maximum safety.
4. Operating Procedures
4.1 Pre-Operation Checks
- Set the manual reset button to the "ON" position to initiate operations smoothly.
- Utilize the test button to simulate an emergency stop, ensuring both channels work in perfect harmony.
4.2 Normal Operation
- During standard operations, both valves function concurrently. A channel malfunction triggers a red alert light and activates the backup system seamlessly, maintaining operation without interruption.
4.3 Emergency Stop
- Engage the E-stop button to immediately cut off the air supply, ensuring the press slide halts instantly for unmatched safety.

5. Maintenance
5.1 Routine Maintenance
- Perform weekly cleaning of the valve's surface and meticulously inspect air hose connections for any potential leaks.
- Conduct monthly assessments of the response time; meticulously record data to ensure precision in maintenance.
5.2 Periodic Service
- Replace seals every six months and clean the spool with anhydrous ethanol to preserve the valve's superior performance and longevity.
- To maintain peak performance and ensure your operations remain flawless, it's crucial to conduct an annual professional calibration of solenoids and sensors for optimal functionality.
6. Troubleshooting
Symptom | Possible Cause | Solution
Valve Inaction: Power off / Coil burnout? Make sure to verify the wiring; replace the coil if necessary to ensure seamless and uninterrupted operation.
Air Leakage: Encounter seal degradation or loose fittings? Secure your peace of mind by promptly replacing seals or tightening fittings to prevent further issues.
Delayed Response: Experiencing low pressure or spool blockage? Boost performance by increasing the pressure or cleaning the spool to ensure swift and efficient operation.
7. Safety Warnings
- 1. NEVER disassemble the valve when under pressure! Always ensure the system is fully depressurized before servicing to guarantee safety and prevent accidents.
- 2. Internal adjustments are strictly prohibited for anyone unauthorized to maintain the system's integrity and ensure the safety of all operations.
- 3. Immediately shut down operations if any abnormal noise or leakage is detected to prevent potential damage or hazardous conditions.
