Manhole cover is installed on the top of tanker.When pressure is massively increased in oil tanker, it can exhaust air by emergency exhausting device,the small plate have inlet P/V vent. It can suitablefor gasoline, diesel,kerosene and other light fuel.There are blinding hole on the manhole cover and it install optic sensor, vapor vent valve, dip tube and other accessories. 1. Emergency Exhausting Device
When the tanker truck in the high temperature condition, 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 difference inside and outside of the tanker , it will automatically inlet or outlet air to adjust the pressure so that can ensure the safety and environment protection.
3.Secondary Open Design
When Open the up binder plate, it will release the pressure out to prevent the operator against dangerous Kick-Back that can e experience due to build up of residual pressure. Technical Data
