3. Installation Instructions
3.1 Pre-Installation
- Ensure the air supply is impeccably clean, dry, and devoid of oil or contaminants for optimal performance.
- Verify that the valve model is compatible with your machine's pneumatic interfaces to ensure seamless integration.
3.2 Installation Procedure
1. Mounting: Securely install the valve in a vertical orientation at the designated position on the press pneumatic control panel using M6 bolts for robust stability.
2. Pneumatic Connections:
- Main Circuit: Connect the air supply to the inlet (P) while linking the actuator (e.g., cylinder) to the outlet (A) for efficient operation.
- Redundant Circuit: Independently connect the backup channel to ensure no cross-interference, maintaining reliability.
3. Electrical Wiring:
- Solenoid Coil Voltage: DC24V±10% or 110V/220V (specify in advance) (Red: +, Black: -) for precise control.
- Ensure reliable grounding by attaching the wire to the equipment's earthing terminal, enhancing safety.
4. Operating Procedures
4.1 Pre-Operation Checks
- Confirm that the manual reset button is firmly in the "ON" position for readiness.
- Activate the test button to simulate an emergency stop, ensuring dual-channel synchronization is flawlessly validated.
4.2 Normal Operation
- During normal operation, both valves function in unison. Should one channel fail, a red alarm light will trigger, and the automatic backup will engage instantly.
4.3 Emergency Stop
- Press the E-stop button to synchronize the cut-off of the air supply, halting the press slide immediately for maximum safety.

5. Maintenance
5.1 Routine Maintenance
- Clean the valve surface weekly and inspect air hose connections for any leaks to ensure uninterrupted performance.
- Test the response time monthly and diligently record the data to maintain top-notch efficiency.
5.2 Periodic Service
- Replace seals every 6 months and cleanse the spool with anhydrous ethanol for optimal operation.
- Annually conduct a professional calibration of the solenoids and sensors to ensure precise functionality.
6. Troubleshooting
Symptom Possible Cause Solution
Valve Inaction Power off / Coil burnout Check wiring; replace coil
Air Leakage: Experiencing issues such as seal degradation or loose fittings? Simply replace the seals or tighten those fittings to restore optimal performance.
Delayed Response: Facing response delays due to low pressure or spool blockage? Elevate the pressure or clean the spool to ensure smooth operation.
7. Safety Warnings
- 1. WARNING: Never disassemble the valve while it is under pressure! Always ensure the system is depressurized before attempting any maintenance.
- 2. CAUTION: Only authorized personnel are permitted to make internal adjustments to this valve.
- 3. ALERT: If you notice abnormal noise or leakage, immediately shut down the system for safety.
