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 air source pressure is within the product's allowable range
- Confirm the air flow direction, the valve body is marked with corresponding port identifiers
2.2 Installation Steps
- Shut off the air 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
- Check all connections for firmness
- Test the adjustment function of the valve to ensure normal operation
2.3 Installation Notes
- Avoid strong impact to the valve body during installation
- Ensure correct port connections, avoid incorrect installation
- Connections must comply with pneumatic system 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
- Check that all connections are firm and free from air leakage
- Test the adjustment function of the flow control valve to ensure normal operation
- Confirm that the adjustment knob rotates flexibly without sticking
3.2 Basic Operation
- Turn on the air supply, the flow control valve is ready for operation
- Rotate the adjustment knob clockwise to reduce air flow
- Rotate the adjustment knob counterclockwise to increase air flow
- Adjust the knob to the required flow rate according to system requirements
- Observe the system operating status to confirm if the flow adjustment is appropriate
3.3 Operation Notes
- Avoid over-rotating the adjustment knob, which may cause damage to internal parts
- Adjustments should be made slowly to avoid sudden flow changes affecting system stability
- If abnormal sounds or unsmooth adjustment 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 adjust the knob to the minimum flow position
4. Maintenance
4.1 Daily Maintenance
