Remove the follower and lock nuts and hope that the threads on the valve are not stripped.

Usually the threads in the nuts die first because they are cut whilst the threads on the valves are (probably) rolled (and are therefore stronger)
Hi Stretch,

Thanks for your feedback. I understand what you wrote here, but I am unclear on what you are suggesting next...

Removing the follower and lock nuts will allow me to see if the condition of the threads.

Assuming we're dealing with stripped threads:

1) Nut is stripped = replace the nut.
2) Valve is stripped = use a thread die on it? Other suggestions?

Sincerely,

Packman
