The former right hand man to FIFA’s scandal tainted president Sepp Blatter was also fined 100,000 Swiss francs ($100,000).
The 55-year-old Frenchman had denied any wrongdoing after he was implicated in the sale of black market sales of tickets for the 2014 World Cup.
A FIFA statement said however that “several other acts of potential misconduct” during his nearly 10-years in office arose as the ethics committee investigated the accusations.
It highlighted “in particular abuse of the FIFA travel expenses policies and regulations, cases involving related-parties issues and the sale of TV and other media rights, and the destruction of evidence”.
FIFA said a sports marketing firm “gained an undue advantage from the selling of FIFA World Cup tickets” and that Valcke had helped.
“Not only did Mr Valcke do nothing to stop these activities, he even encouraged the persons responsible to do so. Furthermore, Mr Valcke repeatedly encouraged them to breach an agreement concluded between FIFA and the sports marketing firm.”
The statement also highlighted a contract for the sale of television and media rights for the 2018 and 2022 World Cups in the Caribbean.
Valcke attempted to grant the rights to “a third party for a fee far below their actual market value and had taken concrete preparatory action in this regard”.
Valcke was also found to have “deliberately” tried to obstruct the FIFA investigation by “attempting to delete or deleting several files and folders relevant to the investigation”.
FIFA said the Frenchman had also cheated on his expenses.
It said Valcke and his family travelled “at FIFA’s expense purely for sightseeing reasons as well as repeatedly choosing private flights for his trips over commercial flights without any business rationale”.
Valcke has also been linked to a $10 million payment made by South Africa to corruption-tainted former Caribbean football chief Jack Warner. US investigators reportedly believe this was a bribe to secure votes for the 2010 World Cup.
FIFA did not say whether this was part of the investigation.
The world football body fired Valcke on January 13, the latest high profile figure to be brought down after Blatter and UEFA chief Michel Platini were banned for eight years for separate ethics violations.
FIFA first suspended Valcke on September 17, when investigators began probing the ticketing scheme.
After ending the inquiry, the ethics committee had called for a lengthy ban and the 100,000 Swiss franc fine.
Valcke has long been a controversial figure in football.
