3. Installation Instructions
3.1 Pre-Installation
- Assure that the air supply is pristine, dry, and devoid of oil/contaminants for optimal operation.
- Ensure the valve model is compatible with the machine's pneumatic interfaces.
3.2 Installation Procedure
1. Mounting: Expertly position and secure the valve vertically at the designated spot on the press pneumatic control panel using M6 bolts.
2. Pneumatic Connections:
- Main Circuit: Connect the air supply to the inlet (P) and the actuator (e.g., cylinder) to the outlet (A) for seamless operation.
- Redundant Circuit: Independently link the backup channel ensuring no cross-interference.
3. Electrical Wiring:
- Solenoid Coil Voltage: DC24V±10% or 110V/220V (specify in advance) for precise requirements (Red: +, Black: -).
- Securely ground the wire to the equipment's earthing terminal for safety.
4. Operating Procedures
4.1 Pre-Operation Checks
- Verify that the manual reset button is set to the "ON" position for readiness.
- Engage the test button to simulate an emergency stop, ensuring flawless dual-channel synchronization.
4.2 Normal Operation
- In optimal operation, both valves function in unison. A failure in any channel will activate a red alarm light and automatically engage the backup system.
4.3 Emergency Stop
- Press the emergency stop button to instantly and simultaneously cut off the air supply, bringing the press slide to an immediate halt.

5. Maintenance
5.1 Routine Maintenance
- Conduct weekly cleaning of the valve surface; meticulously inspect air hose connections for any potential leaks.
- Perform monthly testing of response time and diligently record the data for future reference.
5.2 Periodic Service
- Schedule seal replacements every 6 months and clean the spool using anhydrous ethanol to maintain optimal performance.
- Annually, ensure professional calibration of solenoids and sensors for precision and accuracy.
6. Troubleshooting
Symptom Possible Cause Solution
Valve Inaction: If the power is off or the coil is burned out, ensure you check the wiring meticulously and replace the coil to restore optimal functionality.
Air Leakage: When dealing with seal degradation or loose fittings, it's crucial to replace the seals or tighten the fittings to maintain system integrity.
Delayed Response: In cases of low pressure or spool blockage, elevate pressure levels or clean the spool thoroughly to enhance response time.
7. Safety Warnings
- 1. Safety first! NEVER disassemble the valve under pressure. Always ensure complete depressurization before commencing any servicing.
- 2. Internal adjustments are strictly prohibited for non-authorized personnel to prevent operational hazards.
- 3. Act swiftly! Immediately shut down operations if you notice abnormal noise or leakage to prevent further damage.
