This heavy-duty manhole cover is designed for installation on fuel tanker tops, providing essential breathing and emergency exhaust functions. Its built-in breathing valve maintains balanced pressure between the tank interior and external environment during oil transportation. In case of sudden pressure increases, the emergency exhaust device automatically activates to release internal pressure. The anti-overflow feature ensures sealing integrity even during tanker rollovers, preventing secondary accidents.
Optional configurations include oil/gas recovery valves, anti-overflow probes, and oil measuring ports for enhanced functionality.
