Manhole cover is installed on the top of the tank to prevent the fuel leakage when tank is over rolled,built in P/V vent to adjust the pressure. If there is pressure difference between inside and outside the tank, it will automatically inlet or exhaust air.

When there is accident or under high temperature,it will adjust the pressure to ensure the safety and environmental protection.

It has second class open design, when open the up binder plate.it will let the pressure out to prevent the worker from the pushing over： in the main plate of the manhole, there are two blinding holes can be installed with optic sensor, dip tube or ou terminal vacuum valve according to the user's demands； hooped connecting way, which instead of flange connecting to make the installation more convenient and reliable. It is suitable to transport petroleum, diesel,kerosene and the other light oil and so on.
