This is our ATL check valve with FIA FT3 1999 standard
Details :
The FIA approved check valves are designed for use in vehicles with remote refueling but also for solutions integrated into the tanks where low sealing is required.
Thanks to its sealed O-ring, the valve reduces the risk of spillage, however, please note that the seals must be changed every 18 months and the valve must be recertified every 2 years.
