The Valiants are now nine league games without a win but the outcome could have been worse if it was not for a heroic double save from goalkeeper Ryan Boot in the second half.
The first chance fell the way of the visitors after 11 minutes when Ben Tozer’s long throw caused havoc in the Vale defence and Mark O’Brien failed to test Boot.
A minute later Vale’s top scorer Tom Pope collected the ball and squared it to Michael Tonge whose shot from just outside the area hit a post.
Tozer’s long throw was proving a useful outlet for the Exiles and in the 56th minute the ball eventually fell to Frank Nouble who brought a superb save at close range from Boot.
The rebound fell to O’Brien whose shot through a crowd of players was also saved by the inspired Boot, before the danger was cleared.
