3. Installation Instructions
3.1 Pre-Installation
- Ensure the air supply is pristine, devoid of moisture, and entirely free from oil or contaminants.
- Confirm the valve model corresponds precisely with the machine's pneumatic interfaces.
3.2 Installation Procedure
1. Mounting: Securely anchor the valve in a vertical orientation at the predetermined position on the press pneumatic control panel using M6 bolts.
2. Pneumatic Connections:
- Main Circuit: Connect the air supply to the inlet (P) and link the actuator (e.g., cylinder) to the outlet (A).
- Redundant Circuit: Establish an independent backup channel connection without cross-interference.
3. Electrical Wiring:
- Solenoid Coil Voltage: DC24V±10% or 110V/220V (specify in advance) (Red: +, Black: -).
- Ensure a reliable ground wire connection to the equipment's earthing terminal.
4. Operating Procedures
4.1 Pre-Operation Checks
- Ascertain that the manual reset button is in the 'ON' position.
- Initiate the test button to simulate an emergency stop and verify dual-channel synchronization.
4.2 Normal Operation
- During operation, both valves function in unison. The failure of either channel activates a red alarm light and prompts automatic backup engagement.
4.3 Emergency Stop
- Press the E-stop button to synchronously sever the air supply, bringing the press slide to an immediate halt.

5. Maintenance
5.1 Routine Maintenance
- Weekly, cleanse the valve surface and scrutinize air hose connections for any leaks.
- Conduct a monthly test of response time and meticulously record the data.
5.2 Periodic Service
- Every six months, replace seals and clean the spool with anhydrous ethanol for optimal performance.
- Annually, perform a professional calibration of solenoids and sensors to maintain peak efficiency.
6. Troubleshooting
Symptom Possible Cause Solution
Valve Inaction Power off / Coil burnout Inspect wiring; replace coil promptly
Air Leakage: Experience airtight performance with our Durable G1/2 Solenoid Valve. If leaks occur, it may be due to seal degradation or loose fittings. Simply replace the seals or tighten the fittings to restore optimal functionality.
Delayed Response: Enhance the responsiveness of your system effortlessly. Should you notice a delay, it could be attributed to low pressure or spool blockage. To address this, increase the pressure or clean the spool to ensure seamless operation.
7. Safety Warnings: Prioritize safety with these essential guidelines.
- 1. NEVER disassemble the valve under pressure! Always ensure the system is depressurized before performing any servicing.
- 2. Internal adjustments are strictly prohibited unless performed by authorized personnel.
- 3. Immediately shut down operations if you detect any abnormal noise or leakage, ensuring safety and preventing damage.
