Radiator bleed valves

[HOUSER1980]

I have two Kudox radiators. One in the hallway and another in the bathroom which is a towel rail. I have only just realised that the builder I used put the bleed valves for the radiators in the wrong ones as in the bleed valve for the towel rail is in the hallway radiator and visa versa. Im a pretty confident DIYer but how easy would it be to swap the bleed valves around? The valves are screwed into the radiators.

Thanks

You can turn both valves off on the rads making a note of how many turns you gave them and then swap the vents.
