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 other light fuel。
Emergency open pressure
Max emergency flow rate
Main Size Data
Feature & Benefit
1)Emergency Exhausting Device
when the tanker truck is in 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 it can ensure the safety and environmental 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 experience due to build up of residual pressure.
4) Blinding Hole Design
In the main plate of the manhole cover,There are two blinding holes can be installed with Optic Sensor,Dip Tube or External Vacuum Valve according to user's demand.
5)Aluminum alloy surface is treated by oxidation to improve the anti-corrosion.Can be installed double P/V vent valve according to requirement to increase the flow rate of air.
