Manhole Cover
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 and environment protection. It is suitable to transpore petroleum, diesel, kerosene, and the other light fuel, etc.
* 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.
* With P/V Vent inside
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 and environmental preotection.
* Secondary Open Design
When open the up binder plate, it will release the pressure out to prevent the workers from pushing over.
