SCANVENT P/V valve

Mark IV SuperGreen valve minimizes vapor loss with a patented magnet and air break system. It is completely non-vibrating as it complies with ISO 15364:2007 definition of 2 seconds non-metal-to-metal contact. At the same time, it does not vent tank vapor to atmosphere unless the set pressure is reached. At the set pressure, it vents overpressure unless a true emergency triggers the primary full-capacity unit. INTERANKO and other companies estimate VOC loss on crude oil carriers to be 0.25% of the cargo. Mark IV SuperGreen can eliminate VOC loss for all practical purposes during the voyage. The vent has two discs: a weighted one for thermal fluctuations and a full-flow valve for loading and special cases.

SCANVENT P/V valve (for PO cargo)

When loading PO cargo without cooling, operators must set the high-speed intake and exhaust valve to 0.6 bar. This may require replacing the valve or adjusting its weight, necessitating gas freeing. The Scanjet valve, pre-installed with a 0.6 bar set valve, allows easy handling by locking the existing valve, ensuring quick pressure adjustments and crew safety.
