3. Installation Instructions
3.1 Pre-Installation
- Ensure the air supply is pristine, dry, and devoid of oil or contaminants.
- Confirm valve model compatibility with machine pneumatic interfaces.
3.2 Installation Procedure
1. Mounting: Securely anchor the valve vertically in its designated location on the press pneumatic control panel using M6 bolts for optimal stability.
2. Pneumatic Connections:
- Main Circuit: Directly connect the air supply to the inlet (P) and the actuator (e.g., cylinder) to the outlet (A) for smooth operation.
- Redundant Circuit: Ensure an independent connection for the backup channel to prevent cross-interference.
3. Electrical Wiring:
- Solenoid Coil Voltage: Choose between DC24V±10% or 110V/220V, specifying voltage requirements in advance (Red: +, Black: -).
- Establish a reliable ground by connecting the wire to the equipment earthing terminal, ensuring electrical safety.
4. Operating Procedures
4.1 Pre-Operation Checks
- Verify that the manual reset button is set to the "ON" position, readying the system for operation.
- Activate the test button to simulate an emergency stop, validating the dual-channel synchronization for utmost safety assurance.
4.2 Normal Operation
- During operation, both valves function in concert. Should either channel fail, the system automatically triggers a red alarm light and activates the backup, ensuring continued high-performance operations.
4.3 Emergency Stop
- Engage the E-stop button to simultaneously cut off the air supply, promptly halting the press slide to prevent any mishaps.

5. Maintenance
5.1 Routine Maintenance
- Perform weekly surface cleaning of the valve, inspecting air hose connections meticulously for leaks to maintain top performance.
- Conduct a monthly response time test, documenting results for ongoing system evaluation and reliability.
5.2 Periodic Service
- Every six months, replace seals and clean the spool with anhydrous ethanol to ensure immaculate operational conditions.
- Undertake an annual professional calibration of solenoids and sensors to sustain peak precision and functionality.
6. Troubleshooting
Symptom Possible Cause Solution
Valve Inaction Power off / Coil burnout Check wiring; replace coil
Air Leakage: Seal degradation or loose fittings may lead to unwanted air escape. To ensure optimal performance, replace seals or securely tighten the fittings immediately.
Delayed Response: If you experience a delay, it might be due to low pressure or spool blockage. To restore efficient operation, increase the pressure or thoroughly clean the spool.
7. Safety Warnings
- 1. NEVER attempt to disassemble the valve while it is under pressure! Always ensure the system is fully depressurized before commencing any servicing actions.
- 2. Internal adjustments are strictly prohibited unless conducted by authorized personnel, ensuring safety and product integrity.
- 3. In the event of abnormal noise or leakage, promptly cease operation to prevent further damage and ensure safety.
