Our potential client is a contractor who has it in his bid specs but no particular mechanism is specified.  No idea what the rationale behind the specification is.  While it would certainly be interesting to know and something to discuss with the project manager who authored the bid, this gets beyond the original question which is can it be done on individual valves and, if so, how.

Obviously, if they don't want to use gas in the lab anymore or restrict it to one or two outlets, there are smarter/better ways to do it, but in the absence of specific details, we are dealing with hypotheticals.   If I find out more about the reasoning I'll let y'all know.

1.       Why do you want to lock the valve.
2.       Remember this is a hazardous (explosive) gas. If you are "locking" the valve as part of an energy isolation program to perform maintenance and the valve is part of that lockout boundary your lockout/tag out energy control procedure must be followed.
3.       If you do not have a stored energy control lockout/tag out program you must develop and implement one.
