3. Installation Instructions
3.1 Pre-Installation
- Ensure the air supply is pristine, devoid of moisture, and free from oil or contaminants for optimal performance.
- Verify that the valve model perfectly corresponds with the machine's pneumatic interfaces.
3.2 Installation Procedure
1. Mounting: Rigorously install the valve vertically at the specified location on the press pneumatic control panel using robust M6 bolts.
2. Pneumatic Connections:
- Main Circuit: Connect the air supply to the inlet (P) and link the actuator (e.g., cylinder) to the outlet (A) to ensure seamless operation.
- Redundant Circuit: Establish an independent connection for the backup channel to prevent any cross-interference.
3. Electrical Wiring:
- Solenoid Coil Voltage: DC24V±10% or 110V/220V (specify in advance) (Red: +, Black: -) to meet specific operational requirements.
- Ensure a reliable connection of the ground wire to the equipment's earthing terminal for uncompromised safety.
4. Operating Procedures
4.1 Pre-Operation Checks
- Make sure the manual reset button is set to the "ON" position.
- Activate the test button to simulate an emergency stop and confirm dual-channel synchronization for flawless safety.
4.2 Normal Operation
- During normal operation, both valves operate in concert. A failure in either channel activates a red alarm light and automatically triggers backup activation.
4.3 Emergency Stop
- Engage the E-stop button to simultaneously sever the air supply, bringing the press slide to an immediate halt.

5. Maintenance
5.1 Routine Maintenance
- Meticulously clean the valve surface weekly and inspect air hose connections for potential leaks.
- Conduct monthly tests on response time and diligently record the data for future reference.
5.2 Periodic Service
- Replace seals biannually and clean the spool with anhydrous ethanol for sustained optimal performance.
- Arrange for annual professional calibration of solenoids and sensors to maintain accuracy and reliability.
6. Troubleshooting
Symptom Possible Cause Solution
Valve Malfunction: Immediate corrective action required! Issue - Power off/Coil burnout. Solutions include: Check all wiring meticulously; replace the coil if burnout is confirmed.
Air Leakage Alert: Act promptly to maintain system integrity. Issue - Seal degradation/Loose fittings. Remedial actions - Replace compromised seals or ensure all fittings are securely tightened.
Delayed Response Issue: Optimize performance efficiency. Problem - Low pressure/Spool blockage. Recommended solutions - Increase system pressure or thoroughly clean the spool to restore normal function.
7. Safety Warnings: Essential guidelines for safe operation.
- 1. CRITICAL: Never disassemble the valve while under pressure! Always completely depressurize the system before commencing any service operations.
- 2. Strict Policy: Only authorized personnel may perform internal adjustments to ensure operational integrity.
- 3. Immediate Action: Shutdown the system without delay in the event of abnormal noise or leakage to prevent potential hazards.
