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

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

* 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.
