SDA Shangda waterproof vent valve (pressure relief and explosion-proof valve)is currently widely used, not only in outdoorcommunication equipment, photovoltaic solar energy,electronic instrument products, outdoor ighting, outdoor monitoring equipment,miltary equlpment, chemical packaging containers,etc., but also SDA Shangda waterproof vent valve (pressure relief and explosion-proof valve) is also very suitable for automobiles, because SDA Shangda waterproof vent valve (pressure relief and explosion-proofvalve) has good air permeability and water resistance, sensitive module assemblies must operate accurately and reliably for longperiods of time, even when exposed to harsh operating conditions. Avoidance prevents the ingress of rain, hall, snow, dust, dirt anddebris, and responds quickly and continuously to overpressure and vacuum equalization, thereby protecting the integrity of the seal,extending the service lfe, and preventing water and ditfrom entering the module. The safety and various performances of the car arealso improved to a certain extent, so it will be suitable for the car. So which parts of the car are more suitable for the use of SDAShangda waterproof and permeable valve (pressure relief and explosion-proof valve)?

1. Battery pack protection (ithium battery, aluminate battery,fuel cell) to reduce the risk of battery pack explosion2. Electronic system protection (Controller, DC converter, PDU electrical box),reliably prevent water, liquid, particles into the housing.
to prevent damage to electronic components.
3. Automobile power system protection (DC motor, permanent magnet motor, gear box) to prevent water, oll,foreign mattercrystallization, plaster dust and mud from damaging automobile components, and meet better safety protection standards4.Automobile exterior lighting protection (riont headights,tallights, fog lights) can prevent rain, hail, snow, dust, dint and debris fromentering, and can also quickly respond to the pressure difference that may cause sealing failure.
