Born in Chartres, Duval began his career in karting and in 2002 was the Formula Campus France champion.
In 2003 he was the Formula Renault 2000 France champion.
In 2004 he placed eleventh with two podiums in the Formula 3 Euro Series and tested for Renault F1.
The next year he finished sixth in F3 Euro Series and won a pole at the Macau Grand Prix.
He then moved to Japan where he began racing in Formula Nippon and Super GT.
In 2007 he continued in Formula Nippon and made two starts for A1 Team France in the A1 Grand Prix series in Australia and New Zealand.
He won the 2009 Formula Nippon Championship with four wins driving for Nakajima Racing after finishing second in 2008.

On 11 June 2014, the Le Mans Audi No.
1 driven by Duval was severely damaged, casting doubt whether it could be repaired for the race, or if Audi could build a new car in time, which would start from the back of the field.
Duval was in reasonable condition, considering the magnitude of the accident.
