Key Features
Dual-Function Safety: Combines continuous breathable venting (for pressure equalization) with a high-speed emergency pressure relief function (for explosion prevention).
Designed for Battery Packs: The ideal safety component for battery packs and enclosures in New Energy Vehicles (NEV), hybrids, and large-scale Energy Storage Systems (ESS).
High Airflow & Waterproofing: Provides excellent breathability (≥6,000 ml/min) to prevent condensation while maintaining a high waterproof rating of IP67 (customizable to IP68/IP69K).
Rapid Pressure Relief: In an overpressure event (e.g., thermal runaway), the valve core opens instantly at a set pressure (20-50 Kpa) to safely vent gases.
Robust Composite Construction: Features a durable PP+GF30 body and a 304 stainless steel cap, offering superior impact resistance and thermal performance over standard plastic alternatives.
High Safety Standards: Materials are V0 flame retardant and RoHS 2.0 compliant, ensuring safety and environmental standards are met.
