3. Installation Instructions
3.1 Pre-Installation
- Ensure that the air supply is pristine, devoid of moisture, and completely oil/contaminant-free.
- Ascertain that the valve model aligns precisely with machine pneumatic interfaces.
3.2 Installation Procedure
1. Mounting: Firmly position the valve vertically in its designated spot on the press's pneumatic control panel, utilizing M6 bolts for secure attachment.
2. Pneumatic Connections:
- Main Circuit: Connect the air supply to the inlet (P) and the actuator (such as a cylinder) to the outlet (A).
- Redundant Circuit: Securely connect the backup channel, ensuring no cross-interference.
3. Electrical Wiring:
- Solenoid Coil Voltage: Options include DC24V±10%, 110V, or 220V (must specify beforehand) (Red: +, Black: -).
- Ground wire should be firmly connected to the equipment's earthing terminal.
4. Operating Procedures
4.1 Pre-Operation Checks
- Verify that the manual reset button is in the "ON" position.
- Engage the test button to simulate an emergency stop and confirm dual-channel synchronization.
4.2 Normal Operation
- In normal conditions, both valves operate concurrently. Any channel's failure will trigger a red alarm light and automatic activation of backup systems.
4.3 Emergency Stop
- Depress the E-stop button to simultaneously sever the air supply, causing the press slide to halt immediately.

5. Maintenance
5.1 Routine Maintenance
- Conduct weekly cleaning of the valve surface and inspect air hose connections for potential leaks.
- Monthly, test the response time and meticulously record the data.
5.2 Periodic Service
- Perform seal replacements every six months; cleanse the spool using anhydrous ethanol.
- Arrange for annual professional calibration of solenoids and sensors to ensure precision.
6. Troubleshooting
Symptom Possible Cause Solution
Valve Inaction Power failure / Coil burnout Inspect wiring; replace coil as necessary
Air Leakage: Experiencing issues with seal degradation or loose fittings? Simply replace the seals or tighten the fittings to ensure optimal performance.
Delayed Response: Facing low pressure or a spool blockage? Increase the pressure or clean the spool to restore prompt and efficient response.
7. Safety Warnings
- 1. NEVER disassemble the valve under pressure! Always ensure the system is fully depressurized before undertaking any service work.
- 2. Internal adjustments are strictly prohibited for non-authorized personnel.
- 3. Immediately initiate a shutdown if there is any abnormal noise or leakage.
