Emergency open pressure: 21kpa -32kpa4. Material: Aluminum alloy1.Manhole CoverJialong 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 the other light fuel, etc.2. Benefit &Feature* Emergency Exhausting DesignWhen 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 insideWhen 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 environmental preotection.* Secondary Open DesignWhen open the up binder plate, it will release the pressure out to prevent the workers from pushing over.* Blinding Holes DesignIn the main plate of the Manhole, there are two blinding holes can be installed with Vapor Vent Valve, Optic Sensor, DIP Tube or Exernal Vacuum Valve according to the user's demand.* Larger Angle OpeningThe new designed blinder plate can make the cat hole opening's angle larger than the old one.3.
