3. Select according to the environmental adaptability of the vent valve

      Environmental adaptability generally refers to temperature change resistance, UV resistance, drop resistance, salt spray resistance and moisture permeability. The first four items can be solved by selecting materials. Commonly used materials include nylon mix glass fiber, nickel plated metal copper and alumina. Moisture permeability is an index that needs to be tested. After soaking in water, the air vent valve should be tested. If the attenuation exceeds 30%, it is not recommended.
