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.
