3. Installation Instructions
3.1 Pre-Installation
- Ensure the air supply is pristine, moisture-free, and devoid of oil or contaminants, ready for clean operation.
- Verify that the valve model aligns perfectly with the pneumatic interfaces of the machine for seamless integration.
3.2 Installation Procedure
1. Mounting: Securely fasten the valve vertically in its dedicated spot on the press pneumatic control panel using M6 bolts for stable installation.
2. Pneumatic Connections:
- Main Circuit: Connect the air supply to the inlet (P) and ensure the actuator (e.g., cylinder) links seamlessly to the outlet (A).
- Redundant Circuit: Independently integrate the backup channel to prevent any cross-interference.
3. Electrical Wiring:
- Solenoid Coil Voltage: Compatible with DC24V±10% or 110V/220V; specify in advance. Ensure the red wire is positive and the black wire negative for an impeccable setup.
- Ground the wire securely to the equipment's earthing terminal to maximize safety.
4. Operating Procedures
4.1 Pre-Operation Checks
- Set the manual reset button to the 'ON' position to initiate operations safely.
- Engage the test button to emulate an emergency stop, confirming impeccable coordination of dual channels.
4.2 Normal Operation
- During normal functioning, both valves operate in harmony. A channel failure triggers a red alert light and seamlessly activates the backup system, ensuring uninterrupted performance.
4.3 Emergency Stop
- Press the E-stop button to instantaneously cut the air supply, ensuring the press slide halts immediately for unrivaled safety.

5. Maintenance
5.1 Routine Maintenance
- Weekly: Clean the valve surface and examine air hose connections meticulously for leaks.
- Monthly: Assess the response time diligently, keeping a precise data log for maintenance accuracy.
5.2 Periodic Service
- Every six months: Replace seals and cleanse the spool with anhydrous ethanol to ensure optimal longevity.
- To ensure your equipment runs at its absolute best, it is vital to conduct annual professional calibration of solenoids and sensors. This practice guarantees peak performance and unwavering reliability.
6. Troubleshooting
Symptom Possible Cause Solution
Valve Inaction: Is your valve unresponsive due to power issues or coil burnout? Verify the wiring meticulously and, if needed, replace the coil to restore seamless operation and maintain efficiency.
Air Leakage: Are you facing problems with seal degradation or loose fittings? Secure peace of mind by promptly replacing seals or tightening fittings to prevent further issues.
Delayed Response: If you notice a delayed response due to low pressure or spool blockage, improve performance by increasing pressure or cleaning the spool to ensure swift and efficient operation.
7. Safety Warnings
- 1. Safety first! NEVER attempt to disassemble the valve under pressure. Always ensure the system is completely depressurized before any servicing to guarantee your safety and system integrity.
- 2. To maintain system integrity and ensure safety, internal adjustments should only be conducted by authorized personnel. Unauthorized access is strictly prohibited.
- 3. In case of any abnormal noise or leakage, immediately shut down operations to prevent any potential damage or hazards to the system.
