3. Installation Instructions
3.1 Pre-Installation
- Prioritize air supply quality: ensure it is impeccably clean, dry, and devoid of any oil or contaminants.
- Verify that the valve model precisely matches the machine's pneumatic interfaces for optimal compatibility.
3.2 Installation Procedure
1. Mounting: Secure the valve with unwavering stability by installing it vertically in its designated spot on the press's pneumatic control panel, using robust M6 bolts.
2. Pneumatic Connections:
- Main Circuit: Seamlessly connect the air supply to the inlet (P) and link the actuator (e.g., cylinder) to the outlet (A).
- Redundant Circuit: Independently set up the backup channel to prevent any cross-interference, ensuring reliability.
3. Electrical Wiring:
- Solenoid Coil Voltage: DC24V±10% or 110V/220V (specify in advance) with clear wiring instructions (Red: +, Black: -).
- Ensure reliable grounding by connecting the wire to the equipment's dedicated earthing terminal.
4. Operating Procedures
4.1 Pre-Operation Checks
- Confirm the manual reset button is confidently positioned in the "ON" setting.
- Activate the test button to simulate an emergency stop, ensuring dual-channel synchronization for peak safety.
4.2 Normal Operation
- During regular operations, both valves perform in perfect harmony. Should either channel fail, a red alarm light is triggered, and the automatic backup takes over seamlessly.
4.3 Emergency Stop
- Engage the E-stop button to instantaneously cut off the air supply, bringing the press slide to an immediate halt with precision.

5. Maintenance
5.1 Routine Maintenance
- Perform weekly cleaning of the valve's surface, and meticulously inspect all air hose connections for any leaks.
- Conduct monthly tests on response time, methodically recording all data for analysis.
5.2 Periodic Service
- Every six months, replace seals and cleanse the spool using anhydrous ethanol for optimal performance.
- Annually, conduct a professional calibration of all solenoids and sensors to ensure peak efficiency.
6. Troubleshooting
Symptom Possible Cause Solution
Valve Inaction Power off / Coil burnout Thoroughly check wiring; replace the coil if necessary to restore functionality.
Air Leakage - Potential Causes: Seal degradation / Loose fittings - Solutions: Replace seals or tighten fittings to ensure optimal performance.
Delayed Response - Potential Causes: Low pressure / Spool blockage - Solutions: Increase pressure or clean spool to restore efficient operation.
7. Safety Warnings
- 1. CRITICAL: NEVER disassemble valve while under pressure! Always ensure depressurization before any servicing.
- 2. IMPORTANT: Internal adjustments are strictly prohibited for non-authorized personnel to prevent damage.
- 3. ALERT: Immediately shutdown operations if any abnormal noise or leakage is detected to prevent hazards.
