The MIV series is a plastic vent valve designed for sealed battery enclosures to equalize pressure and reduce condensation while maintaining IP67 and IP69K waterproofing. It operates from -40°C to +125°C and provides a typical airflow of 5.96 L/min at 10 kPa pressure differential, with a venting rate of 20 L/s at 300 mbar. The valve opens at 5 kPa or 12 kPa depending on variant and features a microporous membrane with a 42.00 mm mounting hole diameter. It meets IEC 60068-2-1, 2, 14 for thermal endurance and IEC 60068-2-78 for humidity resistance. The housing is PBT GF30 UL94V0 with an EPDM membrane and stainless steel spring, mounted externally on enclosure top or side surfaces.
This outside-mount plastic vent valve is designed for sealed enclosures, enabling pressure equalization while protecting against water, dust, and environmental contaminants. Installed externally, it simplifies assembly and allows reliable airflow through an integrated microporous membrane, reducing condensation and improving enclosure durability.
