1. Manhole Covers

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 safety and environmental protection. It is suitable to transport petroleum, diesel, kerosene, and other light fuel, etc.

2. Benefit & Feature

* 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 are pressure differences inside and outside the tanker, it will automatically inlet or exhaust air to adjust the pressure so that it can ensure safety and environmental protection.

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

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

* Hooped Connecting
Instead of flanged connecting to make the installment more convenient and reliable.
