Function and Principle of Waterproof Breathable Valve

The waterproof breathable valve is a uniquely designed device that can achieve the function of water molecules being discharged outward and gas molecules being infiltrated inward while ensuring the sealing of the object. Its working principle is based on the natural permeability and diffusion characteristics of gas molecules, which effectively releases the water vapor generated inside the object to the external environment, thereby preventing the shrinkage and mildew caused by the accumulation of moisture inside the object.

The device is mainly composed of two core parts: one is the waterproof layer, which effectively blocks the invasion of external moisture; the other is the gas diffusion layer, which allows gas molecules to pass freely to ensure internal air circulation.

The main function of the waterproof breathable valve is to prevent internal water accumulation or moisture in waterproof products such as shoes, watches, mobile phones, luggage, etc., while enhancing the breathability of the product to ensure that the internal environment always remains dry and comfortable. This not only improves the durability of the product, but also enhances the user experience.

In addition, the waterproof breathable valve is also widely used in outdoor sports equipment, parasols, car seats and other fields. It can effectively improve the use effect and comfort of these products, bringing users a more convenient and pleasant experience.
