Installation instructions
Nylon Breathable Valve is a product designed to prevent internal pressure from being too high or too low due to temperature changes in the product, while maintaining the internal humidity of the product. When installing this product, it is necessary to pay attention to the following aspects.
Firstly, the selection of installation location is very important. You should choose to be as close to the lowest point of the product as possible to ensure that the gas can be discharged normally. It should be avoided to install it in a location that is prone to physical damage.
Secondly, before installation, it should be ensured that there is no pressure or gas inside the product to avoid damaging the valve or causing installation difficulties during the installation process.
Thirdly, it is necessary to install the valve correctly. The correct tools should be used and installed according to the instructions to ensure complete sealing between the valve and the product.
Fourthly, a complete inspection should be conducted after installation. It is necessary to ensure that the valve is in a fully closed state to avoid potential damage to the product. At the same time, the installation position should also be checked to ensure that there is no damage or looseness.
Finally, it is important to regularly check the operation of the product to ensure that it is always in its best condition. If any problems are found, the relevant manufacturer or technical personnel should be contacted for repair as soon as possible.
In summary, proper installation and maintenance of the Nylon Breathable Valve can help protect the product from temperature changes and help it better perform.

How to choose the correct model of air  valve plug 

1. The Ventilation plugs demand is related to the volume of the cavity, the temperature change and the temperature change.                                        
2. Analyze the matching of air permeability between your working chamber and the waterproof and breathable valve. Generally speaking, the product with large air permeability will reduce the waterproof level.                                        
3. To install Ventilation plugs products, IP65
