The latest orders for the valve come from well-known international automakers in Asia and Europe, and represent lifetime sales in excess of €10 million. Production of the FTIVs is scheduled to commence in early 2022 at Pierburg’s plant in Ústí nad Labem in the Czech Republic.
As Dr. Karsten Sonnenschein, head of Pierburg’s Magnetic Valves unit, puts it, “The fact that our new valve has been selling so well so soon after its market debut is due first of all to the extremely compact size of our components, which also happen to weigh less than any competing product.”
In today’s sealed fuel tank systems, overpressure and negative pressure develop depending on the operating situation and ambient temperature. The FTIV is normally a closed valve which opens electrically if required. It also features two mechanical bypasses that regulate the pressure ratio as soon as a defined level of overpressure or negative pressure is exceeded. This is why the FTIV is normally installed between the fuel tank and the activated carbon filter, letting it control the volume stream to the filter, which can be set to a maximum level. On account of its modular design, the FTIV can be equipped for numerous functions and adapted to meet a vast variety of operating specifications.
