3. Installation Instructions
3.1 Pre-Installation
- Ensure that the air supply is pristine, devoid of moisture, and free from any oil or contaminants.
- Confirm that the valve model precisely corresponds with the machine's pneumatic interfaces.
3.2 Installation Procedure
1. Mounting: Securely fasten the valve in an upright position at its designated location on the press pneumatic control panel using M6 bolts.
2. Pneumatic Connections:
- Main Circuit: Link the air supply to the inlet (P) and connect the actuator, such as a cylinder, to the outlet (A).
- Redundant Circuit: Establish an independent connection for the backup channel to prevent cross-interference.
3. Electrical Wiring:
- Solenoid Coil Voltage: Available in DC24V±10% or 110V/220V (please specify beforehand) (Red: positive, Black: negative).
- Securely ground the wire to the equipment's earthing terminal for safety.
4. Operating Procedures
4.1 Pre-Operation Checks
- Ensure the manual reset button is activated in the "ON" position.
- Press the test button to simulate an emergency stop and confirm the synchronization of the dual channels.
4.2 Normal Operation
- During regular operations, both valves function in unison. Should either channel fail, a red alarm light is triggered, and automatic backup activation is initiated.
4.3 Emergency Stop
- Engage the E-stop button to swiftly cut off the air supply, causing the press slide to halt immediately.

5. Maintenance
5.1 Routine Maintenance
- Clean the valve's surface weekly; inspect air hose connections diligently for any signs of leakage.
- Monthly performance tests should be conducted to assess response time, and data should be meticulously recorded.
5.2 Periodic Service
- Replace seals biannually; clean the spool using anhydrous ethanol to maintain optimal function.
- Conduct an annual professional calibration of solenoids and sensors to ensure precision.
6. Troubleshooting
Symptom Possible Cause Solution
Valve Inaction Power off / Coil burnout Inspect and verify wiring; replace the faulty coil if necessary.
Air Leakage: Be vigilant about air leakage issues, as they may arise from seal degradation or loose fittings. To ensure optimal performance, promptly replace seals or tighten fittings to maintain a secure setup.
Delayed Response: If you notice a delay in the solenoid valve's response, it could be due to low pressure or spool blockage. By increasing pressure or cleaning the spool, you can restore the valve's quick and efficient operation.
7. Safety Warnings
- 1. Under no circumstances should the valve be disassembled while under pressure! Always ensure that the system is depressurized before beginning any servicing activities.
- 2. Any internal adjustments are strictly off-limits to unauthorized personnel, ensuring the integrity and safety of the valve operations.
- 3. In the event of hearing abnormal noises or detecting leakages, immediately shut down the system to prevent further damage or safety hazards.
