Benefit & Feature:
1.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.
2.With P/V Vent inside
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 environmental preotection.
