3. Installation Instructions
3.1 Pre-Installation
- Ensure air supply is clean, dry, and devoid of oil/contaminants for optimal performance.
- Confirm the valve model aligns perfectly with the machine's pneumatic interfaces.
3.2 Installation Procedure
1. Mounting: Securely position the valve vertically on the designated spot on the press pneumatic control panel using M6 bolts to ensure stability.
2. Pneumatic Connections:
- Main Circuit: Connect the air supply to inlet (P) and the actuator (e.g., cylinder) to outlet (A) for a seamless air flow.
- Redundant Circuit: Connect the backup channel independently to prevent any cross-interference, ensuring continuous operation.
3. Electrical Wiring:
- Solenoid Coil Voltage: Choose DC24V±10% or 110V/220V (specify in advance) ensuring to connect Red to + and Black to -. Proper grounding to the equipment earthing terminal is essential.
- Reliably ground wire to equipment earthing terminal.
4. Operating Procedures
4.1 Pre-Operation Checks
- Ensure the manual reset button is set to the "ON" position for readiness.
- Engage the test button to simulate an emergency stop, ensuring dual-channel synchronization is functioning perfectly.
4.2 Normal Operation
- During operation, both valves operate in tandem. If either channel fails, a red alarm light is triggered, and the automatic backup is activated instantly.
4.3 Emergency Stop
- Press the E-stop button to synchronously halt the air supply, bringing the press slide to an immediate stop.

5. Maintenance
5.1 Routine Maintenance
- Weekly: Clean the valve surface and inspect all air hose connections for potential leaks.
- Monthly: Test the response time and ensure accurate data recording for optimal performance.
5.2 Periodic Service
- Every 6 months: Replace seals and clean the spool using anhydrous ethanol to maintain efficiency.
- Annually: Professionally calibrate solenoids and sensors to ensure precise operations.
6. Troubleshooting
Symptom Possible Cause Solution
Valve Inaction Power off / Coil burnout Inspect the wiring; replace the coil if necessary to restore functionality
Issue: Air Leakage Potential Causes: Seal degradation / Loose fittings Solution: To restore optimal performance, replace faulty seals or tighten any loose fittings immediately.
Issue: Delayed Response Potential Causes: Low pressure / Spool blockage Solution: Enhance the efficiency of your system by increasing pressure or meticulously cleaning the spool to ensure seamless operation.
7. Safety Warnings
- 1. NEVER disassemble valve under pressure! Prioritize safety by always depressurizing before performing any servicing to avoid hazards.
- 2. Internal adjustments are strictly prohibited for non-authorized personnel to maintain system integrity and prevent mishaps.
- 3. Immediately initiate a shutdown if any abnormal noise or leakage is detected to prevent potential damage or safety risks.
