3. Installation Instructions
3.1 Pre-Installation
- Ensure an immaculate air supply, devoid of moisture, oil, or contaminants, to guarantee optimal performance.
- Verify the valve model's compatibility with the machine's pneumatic interfaces to avoid any misalignment.
3.2 Installation Procedure
1. Mounting: Rigorously secure the valve in its vertical, designated position on the press pneumatic control panel using M6 bolts, ensuring a robust and enduring installation.
2. Pneumatic Connections:
- Main Circuit: Precisely connect the air supply to the inlet (P) while ensuring a flawless linkage of the actuator (e.g., cylinder) to the outlet (A).
- Redundant Circuit: Independently incorporate the backup channel to effectively eliminate any cross-interference issues.
3. Electrical Wiring:
- Solenoid Coil Voltage: Compatible with DC24V±10% or 110V/220V; pre-specify your preference. Ensure red wire is positive and black is negative for a perfect setup.
- Securely ground the wire to the equipment's earthing terminal to ensure the utmost operational safety.
4. Operating Procedures
4.1 Pre-Operation Checks
- Toggle the manual reset button to the 'ON' position to initiate operations seamlessly.
- Engage the test button to simulate an emergency stop, verifying the impeccable coordination and responsiveness of dual channels.
4.2 Normal Operation
- In standard operation, both valves perform in perfect harmony. Should a channel fail, a red alert light triggers and activates the backup system, delivering consistent performance without interruption.
4.3 Emergency Stop
- Instantly interrupt the air supply by activating the E-stop button, ensuring the press slide ceases operation immediately, providing unparalleled safety assurance.

5. Maintenance
5.1 Routine Maintenance
- Undertake weekly cleaning of the valve surface, diligently inspecting air hose connections for any potential leaks.
- Conduct a monthly assessment of the response time; meticulously record data to ensure precision maintenance.
5.2 Periodic Service
- Replace seals biannually and cleanse the spool using anhydrous ethanol to maintain optimal performance and longevity.
- Maintain the pinnacle of performance by ensuring the annual professional calibration of solenoids and sensors, keeping them in optimal condition.
6. Troubleshooting
Symptom | Possible Cause | Solution
Valve Inaction: Power off or coil burnout could be the culprit. Ensure reliable operation by verifying wiring or replacing the coil if necessary.
Air Leakage: If seal degradation or loose fittings arise, secure flawless function by promptly replacing seals or tightening fittings.
Delayed Response: Facing low pressure or spool blockage? Revitalize performance by elevating pressure or cleaning the spool for expedited operation.
7. Safety Warnings
- 1. NEVER attempt to disassemble the valve under pressure! Always ensure full depressurization before servicing to uphold safety.
- 2. Internal adjustments must be strictly avoided by non-authorized personnel to preserve system integrity and safety.
- 3. Immediately cease operations if abnormal noise or leakage is detected to avert potential damage or hazards.
