The tickets will be of the reduced variety of £25 for adults and £12 for juveniles and senior citizens.
They will be on sale from 7am online or 9am through the box office and call centre.
Chelsea have won their Champions League group already and Valencia are likey to be bottom of the four-team group.
So by opening ticket sales early smacks as a measure of desperation by Chelsea to fill the 43,000 stadium.
Chelsea fell foul of thier desire to fleece fans by charging full price for the opening game against Rosenborg.
The half-empty stadium was a factor in Jose Mournho's departure as the visitors took full advantage of the debacle going on at the Bridge to snatch a deserved 1-1 draw.
The following game against Schalke saw ticket prices reduced to that of Carling Cup matches and now the match against Valencia, which will see Chelsea field a less than full-strength side will again be cut-price.
It is hoped that the powers that be will see the wisdom of changing their ticketing policy next season to reflect the growing frustration by true Blue to the high prices.
