Did you know
- Scanjet, a brand now under Alfa Laval, has been a supplier of marine tank venting equipment for over 50 years. Alfa Laval acquired Scanjet in Q3 2022, integrating their tank management solutions into Alfa Laval's marine offerings.
- Within Alfa Laval's broader valve portfolio, the Scanjet Pressure-Vacuum (PV) Valves are specifically designed for marine tank venting, distinguishing them from other Alfa Laval valves like the Unique RV-P regulating valves used in hygienic processing or the various safety and relief valves for general pressure control in pipelines and vessels.
- The Scanjet high-velocity PV valve is designed to minimize VOC (Volatile Organic Compound) loss and ensure non-oscillating performance, contributing to efficient cargo conservation and reduced emissions. Its design, featuring a dual-disc arrangement and a patented combination of magnetic force and air braking, allows for stable operation and low maintenance.
| Model | Primary Function | Key Feature | Compliance |
|---|---|---|---|
| Alfa Laval (Scanjet) High-Velocity PV Valve | Ongoing pressure control and VOC management in cargo tanks | Patented magnet power and air brakes for non-oscillating behavior; dual-disc arrangement for thermal fluctuations and full-flow loading. | IMO Circ. 677, Rev. 1; ISO 15364:2021; ISO 16852:2016 |
| Alfa Laval (Scanjet) In-Line P/V Valve Type FPS | Automatic pressure and vacuum control in cargo tanks and inert gas (I.G.) mains | Automatic weight-loaded mechanism for dynamic response to pressure changes; in-line installation. | Not specified in search results |
| Alfa Laval PV Breaker | Last resort safety device for excessive pressure or vacuum conditions in cargo tanks | Activates when PV valves cannot maintain pressure within accepted tolerances, equalizing pressure by admitting or releasing air. | Mandated by IMO regulations |
