Looking for an old angle valve for steam radiator

Hi all,

I'm looking to replace this old valve which has a damaged thread.


I've looked in a plumbing supply house, and online.
To my naked eye, the type of union connection that's here is not available online, but I could be wrong.
Maybe I just don't know the right name of this type of valve?
Any advice would be greatly appreciated.

    If you replace the valve, then the spud part of the union will have to be changed as well-a big chore!!

    I think the valve and spud need to be changed...

    Looks like an internal pipe wrench should help get that spud out (and another one in). I'll give that a shot, would rather not risk having the radiator leak.

    Thanks for the help guys!

    looks like 1 1/4 to 1 1/4 they sell them all day long at the supply houses, you might want to pb blast over night to get the spud and valve off tho

    Well then, @nicholas bonham-carter , you were not joking :)
    Thanks @Newagedawn, it was a 1 1/4.



    After the rusted inner edges of the spud just got shaved off by the inner pipe wrench, I had to resort to drilling the side of the spud from end to end, hammering a demo screwdriver in there, then using the large pipe wrench on the screwdriver to force the spud to turn. It did budge eventually and here it is :)

    Thanks again all.

    Do I use tape on the spud/valve? pipe dope? nothing?

    I've not done this but from what I gather you would dope the male threads, possibly lay some wicking in them first if you think they need that, and leave the mating surfaces as is - nothing on them. Someone can correct me if I'm off ...

    A picture is worth a thousand words! Good idea about the drill and screwdriver.—NBC
