Main features
Manhole is installed on the top of the tank, built-in pressure& vaccum vent & emergency vent.
Advantage
1. Pressure & vaccum vent, while inside pressure higher than 6-8 Kpa or lower 2-3Kpa than the outside, will be open to
balance the different pressure. While the difference pressure less than -2~6Kpa, the P/V vent will be closed to keep the
product not volatilized.
2. Automatic sealing of P/V vent in a roll over situation prevents dangerous and splliage.
3. When the inside pressure is higher 21-32kpa than the outside. The emergency vent will be open automatically to keep tank
safe. The vent capacity is 7000M3/h.
4. Two-stage opening allows safe release of residual compartment pressure before fully opening the fill cap.
5. Easy maintenance, convenience, safety.
6. Working pressure:0.6Mpa
