This aluminum manhole cover is designed for installation on tanker trucks, providing essential internal breathing and emergency exhaust functions. During fuel transportation, the internal breathing valve maintains pressure equilibrium between the tank interior and exterior environment. In cases of sudden pressure increase, the emergency exhaust mechanism activates automatically to release internal pressure.
The built-in anti-overflow safety feature ensures reliable sealing even in accident scenarios, preventing potential hazardous situations.
