MAXIMUM SAFETY, MINIMUM VAPOR LOSS, PROVEN PERFORMANCE
The SCANVENT high‑velocity pressure/vacuum (P/V) valve is engineered to deliver best‑in‑class vapor control, combining advanced safety performance with industry‑leading reliability. Developed through extensive research, SCANVENT achieves the optimal balance between minimum vapor loss and stable, non‑oscillating behavior—even under demanding conditions. The SCANVENT High Velocity P/V Valve is designed for operators who demand reliability, efficiency, and compliance—without compromising on performance. Developed through extensive research and field experience, SCANVENT sets a new standard in non‑oscillating vapor control, delivering unmatched stability and ultra‑low leakage in all operating conditions. Whether installed on tankers, offshore units, or land‑based industrial facilities, SCANVENT ensures optimal VOC handling, improved safety, and reduced operating cost.By controlling the pressure and vacuum, PVs minimize the loss of volatile substances through evaporation, which is crucial for maintaining product quality and reducing environmental impact.
True Non‑Oscillating PerformancePatented magnet‑powered damping ensures smooth, stable operation, meeting the two‑second, no‑metal‑to‑metal‑contact requirement in ISO 15364:2021.
Minimal Vapor LossEngineered to protect the tank atmosphere—VOC or inert gas—keeping pressure above the required Target Pressure (IMO MSC/Circ. 680).
Lowest Possible LeakagePrecision‑engineered seats and discs, combined with quality materials, ensure industry‑leading tightness.
Designed for Demanding EnvironmentsFrom marine vessels to refineries, terminals, and industrial sites—SCANVENT delivers reliable performance wherever pressure/vacuum protection is critical
The SCANVENT P/V valve meets or exceeds all current and upcoming regulations, including:
When the opening setting is reached, the valve lifts fully and instantly thanks to its magnet/weight/booster combination, ensuring high ventilation capacity and safe loading operations.
A dedicated VOC valve manages small thermal venting flows during transit, re‑seating at its defined opening pressure. This guarantees:
PANEL 1 — Optimized Operation • Tank VOC/inert gas pressure stays above the required threshold.
PANEL 2 — Full‑Lift Performance • Instant, high‑capacity venting during loading
PANEL 3 — Dedicated VOC Nozzle • Separate nozzle for small thermal venting flows—no main valve activation.
The result of this simple but efficient design is optimum VOC handling and minimum use of the inert gas plant – Flemming Hvam, Product Manager
