3. Installation Instructions
3.1 Pre-Installation
- Ensure air supply is pristinely clean, dry, and devoid of any oil/contaminants.
- Verify that the valve model seamlessly aligns with the machine's pneumatic interfaces.
3.2 Installation Procedure
1. Mounting: Securely affix the valve vertically in the designated position on the press pneumatic control panel using M6 bolts for maximum stability.
2. Pneumatic Connections:
- Main Circuit: Connect the air supply to the inlet (P) and the actuator (e.g., cylinder) to the outlet (A) with absolute precision.
- Redundant Circuit: Independently establish a connection for the backup channel, ensuring no cross-interference.
3. Electrical Wiring:
- Solenoid Coil Voltage: Choose between DC24V±10% or 110V/220V (specification required in advance). Wire configuration (Red: +, Black: -).
- Ensure a secure grounding of the wire to the equipment's earthing terminal for safety.
4. Operating Procedures
4.1 Pre-Operation Checks
- Confirm that the manual reset button is firmly in the "ON" position.
- Activate the test button to simulate an emergency stop, verifying flawless dual-channel synchronization.
4.2 Normal Operation
- During regular operation, both valves function concurrently. Should either channel fail, a red alarm light activates, and the automatic backup takes over.
4.3 Emergency Stop
- Engage the E-stop button to synchronously cease the air supply, bringing the press slide to an immediate halt.

5. Maintenance
5.1 Routine Maintenance
- Weekly, clean the valve surface and inspect air hose connections for potential leaks.
- Monthly, test the response time and meticulously record the data for performance tracking.
5.2 Periodic Service
- Every 6 months, replace seals and meticulously clean the spool with anhydrous ethanol for peak performance.
- Conduct annual professional calibration of solenoids and sensors to ensure precision.
6. Troubleshooting
Symptom Possible Cause Solution
Valve Inaction Power off / Coil burnout Thoroughly check wiring; replace the malfunctioning coil.
Air Leakage: An issue often arising from seal degradation or loose fittings. To address this, promptly replace the seals or ensure all fittings are tightened to prevent further complications.
Delayed Response: Typically due to low pressure or spool blockage. Elevate the pressure levels or meticulously clean the spool to restore optimal functionality.
7. Safety Warnings
- 1. UNDER NO CIRCUMSTANCES should you disassemble the valve while under pressure! Always ensure the system is fully depressurized before undertaking any servicing activities.
- 2. Unauthorized personnel are strictly prohibited from making internal adjustments to the valve system.
- 3. Should you observe any abnormal noise or leakage, execute an immediate shutdown to prevent further damage or safety hazards.
