large gate valve repair?
(OP)
Are there any good manuals or videos that cover repairs to gate valves? I have a 12" gate valve where the threaded rod that the brass 2" nut slides onto and then the smaller nut holds it on has broken off. It is functional right now if gentle but I don't want to damage it any more. Anyones help would be appreciated.

What is your timeframe? When do you need to start? How long can you stand being shutdown for? How much variation can you tolerate in resuming operations? That is - if you fail in the repairs yourself using a temporary fix or local talent and local labor or your own millwrights/operators to fix it, how long can you tolerate delays before getting (more expensive!) contract labor in place?
Do you have all replacement parts on hand? Seals, nuts, bolts, studs, washers, new brass fitting, gaskets, etc? Do you have the original drawings on hand? Can you get them? Do you have a replacement valve ready or available? How long will it take to get the replacement valve to your site?
Where are you, and what resources (machine shop or millwright tools) do you have on hand? Crane available? Compressed air? welding gas and welders available? What electric power, lights, rain covers, and laydown area do you have?
