The main charactenistics of waterproof ventilation valve (respirator), waterproof and dustproof grade IP67 ~IP68; The valve bodyquickly recovers ventlation after contacting liquid. High air permeability can reduce the stress of the casing sealing strip by balancingpressure. The protective film with hydrophobic oil structure is embedded in the shelland has the charactenistics of inertness, unity andchemical resistance. It can even prevent salt crystals, Moisture and water vapor permeability, The threaded shell is equipped with
fluorine sealing ringIn addition, the role of waterproof ventilation valve has a lot, so the use of time must be timely to understand. So, what is the generalrole of waterproof ventilation valve?

function 1. can protect the equipmentfrom water entering: waterproof is the main function of waterproof ventilation valve, and the useeffect of many equipment will be affected by water. Once the equipment into the water, at this time of the equipment use effect will bebad. Therefore, in order to prevent the equipment from entering the water,it is necessary to actively install a waterproof ventilationvalve on the equipment.
function2. dust-proof effect is very g0od: once the equipment into the dust, the equipment is prone to non-operation,so that theequipment is very unfavorable. Therefore, it is very good to install waterproof ventilation valve for equipment. Waterproof ventilationvalve in the role of dust is also great, so the use of this product in the industrial field is very extensive.function 3.to prevent equipmentfogging and condensation. if the equipment is condensed orfogged, the service ife of the equipmentwill be affected. Therefore, many devices are installed waterproof ventilation valve. This is because the waterproof ventlation valveanti-fog and anti-condensation effect is very good, so the product is widely used.In short, there are many functions of the waterproof ventlation valve,so the use of the waterproof ventilation valve can be seen in
many places, but the correct method must be used when using it.
