2. Installation Instructions
2.1 Pre-installation Preparation
- Ensure the installation environment meets the product working conditions
- Check that the product packaging is intact and undamaged
- Prepare necessary installation tools and accessories
- Confirm that the power supply voltage matches the solenoid valve rated voltage
- Confirm the air flow direction, the valve body is marked with corresponding port identifiers
2.2 Installation Steps
- Shut off the air supply and power supply to ensure safety during installation
- Install the valve body in the pneumatic circuit according to the air flow direction
- Use appropriate tools to connect the input port to the air source
- Connect the output port to the equipment requiring control
- Use sealing tape or sealant to ensure tight connections and prevent air leakage
- Connect the power supply line, paying attention to polarity (if applicable)
- Check all connections for firmness
2.3 Installation Notes
- Avoid strong impact to the valve body during installation
- Ensure correct port connections, avoid incorrect installation
- Power connections must comply with electrical safety standards
- Installation environment should avoid high temperature, humidity, and corrosive gases
- Regularly check the tightness of installation connections

3. Usage Methods
3.1 Pre-operation Check
- Confirm that the air source pressure is within the product's allowable range
- Confirm that the power supply voltage matches the solenoid valve rated voltage
- Check that all connections are firm and free from air leakage
- Test the working status of the solenoid valve
3.2 Basic Operation
- Turn on the power, the solenoid coil is energized, the valve opens, allowing air to pass through
- Turn off the power, the solenoid coil is de-energized, the valve closes, stopping air flow
- Control the air flow by controlling the on/off of the power supply according to system requirements
3.3 Operation Notes
- Avoid frequent switching of the solenoid valve, which may shorten service life
- Ensure stable power supply voltage, avoid voltage fluctuations
- If abnormal sounds or overheating are found, stop using immediately and inspect
- When not in use for a long time, it is recommended to turn off the air supply and power supply

4. Maintenance
4.1 Daily Maintenance
- Regularly clean the valve body surface to remove dust and oil
- Check if the temperature of the solenoid coil is normal
- Test the on/off performance of the solenoid valve
4.2 Regular Inspection
- Check the sealing status of connection ports monthly
- Inspect the insulation performance of the solenoid coil quarterly
- Check the wear condition of internal seals every six months
- Perform a comprehensive cleaning and maintenance annually
4.3 Maintenance Notes
- Use neutral detergent for cleaning, avoid using corrosive solvents
- Ensure the air supply and power supply are turned off during maintenance to avoid accidental activation
- If parts need to be replaced, it is recommended to use original accessories
- When the solenoid coil is damaged, it should be replaced as a whole, avoid self-repair
