SDA Shangda waterproof breathable valve and explosion-proof pressure relief valve for new energy vehicle electric drive EDV (gearbox/DC motor/permanent magnet motor) system protection.

With the continuous improvement of new energy engineering and technical personnel’s requirements for motor performance and safety, the motor, as the core drive system of new energy vehicles, faces harsh working conditions and non-vacuum airtight changes, which affects the performance of the vehicle. SDA Shangda waterproof ventilation valve and explosion-proof pressure relief valve metal products are protective products designed for high-power and high-current vehicle electric drive systems. The metal material is more suitable for the motor sealing cavity, reducing condensation, preventing oil and dust, waterproof and breathable, balancing internal and external pressure, and improving the electric drive performance of new energy vehicles.

SDA Shangda waterproof vent valve, explosion-proof pressure relief valve metal protection products, waterproof and breathable, reduce condensation, oil and dust, balance internal and external pressure (stress):

1. Adopt high-temperature resistant materials to deal with harsh working conditions;

2. Pressure relief ventilation, release the air pressure generated by the change of motor working condition, and avoid damage to precision parts;

3. Dust, reduce condensation, balance the pressure inside and outside the motor cavity (stress);

4. Excellent design structure to solve the safety problems caused by the sudden increase of internal air pressure in the work of electric drive;

5. To achieve customized, diversified design to meet customer needs.
