Product Description


YOJE RKG series manhole cover 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.

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.
