VRLA battery exhaust valve
Key Features & Benefits:
1. Intelligent Pressure Regulation
2. Triple-Layer Safety System
Acid Mist Filtration – PE/ceramic filter captures 99%+ corrosive fumes
Flame Arrestor – UL94 V-0 certified, prevents external ignition
Auto-Resealing – Instant closure after pressure release
3. Extreme Environment Durability
Temperature range: -40°C to +120°C
Vibration resistant: Withstands 50G shock (ideal for automotive/industrial use)
Corrosion-proof: PP/ABS material
4. Maintenance Optimization
Reduces electrolyte loss by up to 40% vs. standard valves
Extends battery cycle life by 30%+
The Explosion proof vent plug is sturdy and durable with an excellent finish that gives a long service life. There is a built in PE filter that ensures it provides a splash proof or anti splash feature. It is because of the filter that corrosive acid fumes do not escape and become the cause of a fire hazard and helps keep the battery exterior completely dry. By arresting the acid fumes damage to costly equipment around the battery can also be prevented.
