Shangda SDA waterproof and breathable (waterproof and breathable valve) protection scheme provides reliable protection againstnew energy vehicle battery PACK. Even if exposed to harsh working conditions, sensitive module components must operateaccurately and reliably for a long time. Effectively prevents the intrusion of rain, hail,snow, dust, dint and debris, and can quickly andcontinuously respond to overpressure and vacuum equalization,thereby protecting the integrity of the seal, extending the service life.and preventing water and dirt from entering the module.

Now in the market competion, SDA Shangda pressure relief explosion-proof valve,is an industry pressure relief explosion-proofvaive manufacturer,in line with new energy national standards, with safety protection performance., improve vehicle performanceSDA Shangda pressure relief and explosion-proof valive protects the battery PACK, can quicKly relieve pressure and prevent overfiowand explosion, and is a special explosion-proof and breathable component for the battery that can be waterproof and dustproof. Innormal operation, it can quickly ventilate, and when the gas reaches the critical value of the explosion-proof point,it will instantly passthrough the outside, and a large amount of gas will be discharged to quickly release the strong pressure inside the cavity to avoidexplosion or reduce explosion damage.
