The terms Vx and Vy are not used in transport category aircraft.  The max flap
speeds are, or course, different for each flap setting.

The flap speeds for a basic  727-200 are:

230, 215, 205, 185, 185, 175  (KIAS)
for flaps
2,    5,     15,    25,   30,   40, respectively.

Some 727's have a flap 20 position, and most operators do not use the flap 40
position.  Some 727-200 Advanced have higher flaps speeds, e.g. 245 for flaps
2.
