How to Remove a Valve Core?

[Nancy]

The method to remove a valve core is: 1. Use a professional removal tool, such as a valve screwdriver, and turn it counterclockwise to remove the valve; 2. Use a valve core tool, align the groove with the valve core, and turn it counterclockwise to remove the core. The valve core is installed inside the valve stem and functions as a one-way valve, preventing air leakage from the inner tube and allowing for pressure checks and adjustments. Precautions when removing the valve core: 1. A few drops of oil can be added before removal; 2. Avoid using excessive force during the removal process. The main types of valve cores include British, American, French, German, and Italian valve cores.
