Wowhead doesn't list a vendor for the PvP gear at 85. Perhaps they are located in Tol Barad which would explain your inability to locate them.
For those who are apparently unable to comprehend what the OP was asking, and no it isn't on the front page for you "go read the front page" asshats, the OP would like to know if the following vendors exist on the PTR or in 4.0.3a:
http://cata.wowhead.com/npc=44246 Alliance Justice
http://cata.wowhead.com/npc=44245 Alliance Valor
http://cata.wowhead.com/npc=46555 Horde Justice
http://cata.wowhead.com/npc=46556 Horde Valor
Those are the NPCs that sell gear that is obtained for Justice or Valor points located in SW or Org.
