Product Description

Manhole Cover is installed on the top of the tanker to prevent the inside fuel from leakage when the tanker is
over rolled. With P/V vent inside to adjust the pressure. When there is pressure  differences inside and outside the tanker, it will automatically inlet or exhaust air to adjust  the pressure so that it can ensure the safety 
andenvironment protection. It is suitable to transpore petroleum, diesel, kerosene, and the other light fuel, etc.

Features
1.  Emergency Exhausting Design 
When the tanker truck is in high temperature condition, the manhole will automatically exhaust  the air inside to release the 
pressure, ensuring the safety of the tanker.

2.  With P/V Vent inside
When there is pressure differences inside and outside the tanker, it will automatically inlet or exhaustair to adjust the pressure so that it can ensure 
the safety and environmental preotection.

3. Secondary Open Design
When open the up binder plate, it will release the pressure out to prevent the workers from pushing  over.

4.  Blinding Holes Design
In the main plate of the Manhole, there are three blinding holes can be installed with Vapor Vent Valve,Optic Sensor, DIP Tube orexernal Vacuum 
Valve according to the user's demand.

fuel tanker Manhole Lid  is installed on the top of oil tanker. It is the internal inlet of loading, checking vapor recovery and tanker maintenance. It can protect the tanker from emergency.
Normally, the breathing valve is closed. However, when load unload oil external temperature changes, and the pressure of tanker will change such as air pressure and vacuum pressure. The breathing valve can automatically open at a certain air pressure and vacuum pressure to make the tank pressure in normal condition. If there is emergency like roll over situation, it will automatically close and it also can avoid the tanker explosion when in fires. As the emergency exhausting valve will automatically open when tank truck interior pressure increases to a certain range.
