The waterproof ventilation valve is a device that can realize the outward expansion of water molecules and the expansion of gas in the sealed state of the object. It is mainly composed of waterproof breathable membrane, valve body and valve core and other components, in which the waterproof breathable membrane occupies its main production cost. There are many kinds of waterproof ventilation valves, which can be divided into metal waterproof ventilation valves and plastic waterproof ventilation valves according to different materials. According to different installation methods, it can be divided into snap-in waterproof ventilation valve, threaded waterproof ventilation valve, press-in waterproof ventilation valve, etc. According to different gas flow directions, it can be divided into two-way waterproof ventilation valve and one-way waterproof ventilation valve. According to different connection methods, it can be divided into welding type waterproof breathable valve, injection molding type waterproof breathable valve, bonding type waterproof breathable valve, etc.

The core part of the waterproof and breathable valve is a waterproof and breathable membrane, which is made of expanded polytetrafluoroethylene film (EPTFE) and has a mesh of micropores with a micron diameter. This structure is easy to penetrate the air, and liquid water can not pass through, at the same time, the film can also capture particles as small as 0.1μm, can prevent fine salt crystals, dust into the sealed cavity, so as to achieve the purpose of waterproof, dustproof, breathable.

In short, waterproof ventilation valves are widely used in many fields, such as medical equipment, electronic equipment, automobile manufacturing, lighting and photovoltaic power generation.
