In regular, hybrid and electric vehicles, it is essential that electrical components and electronic modules are protected effectively.These sensitive module components must guarantee long-term operational reliability even when exposed to harsh operatingconditions. Whether the car is driving or parked, it can quickly and continuously balance the overpressure and vacuum generated byenvironmental changes., Reliably prevents water, hazardous vehicle liquids and particles from entering the housing and preventingdamage to electronic components. Sunda SDA provides a solution that is flexible for use with any electrical component or electronicmodule using an embedded type.
Shangda waterproof ventilation valve (snap-in waterproof ventlation valve, explosion-proof pressure relief valve) with protectiveventlation components according to the characteristics of the auto parts unit protection and ventlation and different, waterproof, oi-proof, dust-proof and breathable, rapid gas exchange to avoid vehicles from water, oil. The pollution of automobile emissions and dustreduces fogging and condensation, improves the product quality of automobile parts and vehicles and prolongs the service life.

Shangda waterproof ventilation valve (snap-in waterproof ventilation valve,explosion-proof ressure relief valve) protectionfor electronically controlled ECV(-controlleriDC converter-PDU high-voltage configuration electric box): protection solutionfor electronic control system of new energy vehicles, increase reliability, and improve vehicle quality and image1. Shangda Technology ECV series breathable protection products are based on the electronic control system, which is easy togenerate heat during long-term work. Under the condition of excessive internal pressure, it can quickly balance intemal and externalpressure, reduce water vapor and mist, and reduce condensation. Waterproof breathable valve.
2. new snap-type plastic waterproof breathable valve,compared to foreign industies choose material better resistance,cover design
protection is higher.
3. The new material structure design and light appearance of the waterproof and breathable valve made of metal and plastic materialsare superiorto the traditional balance valve. The cover design is conducive to the installation of the machine, preventing the machinefrom lifting and falling off during installation, and improving the installation efficiency.

Shangda waterproof ventilation valve (Snap-in waterproof ventilation valve, explosion-proof ressure relief valve)waterproot
and dustproof, pressure relief breathable,efficient protection:
1,the use of e-ptfe fim, block external moisture, dust and pollution particles, keep the component cavity clean;
2. Applicable to -40 C-125 C working environment;
3, pressure relief breathable, release parts due to temperature, pressure generated by the intemnal pressure,to avoid damage to the
precision components;
4. rapid ventilation, high ventilation to solve the electric drive system in the work due to the sudden increase in the pressure caused
by the safety problems;
5. Threaded and snap-in installation is not only easy to install, but also free from maintenance.
