3. Installation Instructions
3.1 Pre-Installation
- Ensure the air supply is immaculate, devoid of any moisture, oil, or impurities for optimal performance.
- Verify that the valve model aligns perfectly with the machine's pneumatic interfaces for a seamless installation.
3.2 Installation Procedure
1. Mounting: Position the valve vertically on the press pneumatic control panel and secure it meticulously with M6 bolts for a reliable and sturdy setup.
2. Pneumatic Connections:
- Main Circuit: Ensure flawless connection of the air supply to the inlet (P) and that the actuator links seamlessly to the outlet (A).
- Redundant Circuit: Independently integrate the backup channel to eliminate any cross-interference.
3. Electrical Wiring:
- Solenoid Coil Voltage: Choose between DC24V±10% or 110V/220V compatibility and ensure red is positive and black is negative for an impeccable electrical setup.
- For ultimate safety, securely ground the wire to the equipment's earthing terminal.
4. Operating Procedures
4.1 Pre-Operation Checks
- Verify the manual reset button is switched to the "ON" position to start operations effortlessly.
- Engage the test button to simulate an emergency stop, ensuring the perfect synergy of dual channels.
4.2 Normal Operation
- During standard operations, both valves function harmoniously. In case of a channel failure, a red alert is activated, and the backup system automatically engages for uninterrupted efficiency.
4.3 Emergency Stop
- Press the E-stop button to cut off the air supply instantly, guaranteeing the press slide stops immediately to maintain exceptional safety.

- Biannually, replace seals and cleanse the spool with anhydrous ethanol to maintain the valve's optimal performance and longevity.
Ensure top-tier performance by committing to an annual professional calibration of solenoids and sensors. This proactive step guarantees reliability and enhances operational efficiency.
6. Troubleshooting
Symptom | Possible Cause | Solution
Valve Inaction: Facing power issues or coil burnout? Ensure seamless operation by verifying wiring and replacing the coil if necessary.
Air Leakage: Experiencing seal degradation or loose fittings? Attain peace of mind by promptly replacing seals or tightening fittings to maintain system integrity.
Delayed Response: Is low pressure or spool blockage affecting performance? Optimize response time by increasing pressure or cleaning the spool for smooth, efficient operation.
7. Safety Warnings
1. NEVER disassemble the valve while under pressure! Ensure the system is fully depressurized before servicing to maintain utmost safety and prevent accidents.
2. Unauthorized personnel must refrain from making internal adjustments to uphold the system's integrity and ensure safety at all times.
3. If any abnormal noise or leakage is detected, immediately shut down operations to prevent potential damage or hazards, safeguarding both personnel and equipment.
