SCANVENT HIGH VELOCITY P/V VALVES
It features a combination of magnet power and air breaks, which are unique and patent applied for. It is truly non-oscillating as it complies with the two second no-metal-to-metal contact definition from ISO 15364:2007.
At the same time it does not emit tank vapour to atmosphere unless the set-pressure is reached, at which point it will only emit excess pressure, unless a true emergency is happening when the primary full capacity unit will open.
INTERANKO and others have estimated the VOC loss on the crude carrier to equal 0.25% of the cargo. The Mark IV SuperGreen can reduce VOC loss for all practical purposes to nil during voyage.
The vent features two discs: a small weight loaded one for thermal variations during voyage and full flow valve for use during loading and special occasions.
