Radiator Valves leaking

I have a customer with some radiator valves that are either leaking or stuck. Another local company has already tried to rebuild the leaking ones and they are actually worse now. This is two pipe steam, and the radiators are all recessed into the walls.

I was wondering if anybody knows of anyplace I could possibly source parts for these to rebuild them. I've been looking on line with no luck, no supply houses in my area are any help at all unfortunately. Not sure if this helps, but the home was built in 1940 and I'm told these are original. I've never seen any quite like them. I will include pictures for your viewing pleasure. Thanks in advance for any help!

    Looks like a Trane convector so my guess would be that the valves are also Trane.

    Your pictures are tiny but they look like they are a special version of these with a banjo bolt to connect to the convector:

    What is the logo on the valve body? Post a closeup.

    Those are the best pics I have of the logo. It kind of looks like an acorn. I wonder why they are showing up small, it’s not that way on my end. 

    Anyway, they are definitely convectors. I watched the video. I’m fairly certain those are not the same valves. The stem is definitely different.

    Where, exactly, are they leaking from? Unless the metal has somehow become damaged, it should be possible to rebuild them without replacing any parts -- just packing or, possibly, a gasket or o-ring.

    Jamie, 

    They are leaking from the packing around the stem. As per my initial post, another contractor has already tried to repack them. 

    I’ve never seen valves quite like these. I was just curious if anybody else had and if they could identify who made them and if it was possible to rebuild them. 

    So far I’m striking out. Even if I was going to replace the entire valve I have no idea where one could be found to replace these.

    you'd have to retrofit it to a valve and a connection to the convector if you replace them(or replace the convector element). Are they packed valves or are they some sort of a bellows valve like the Trane valves? even if they aren't train, they may be a similar design.

    Maybe the a is american radiator.

    I was just speculating until someone who knew came around. i wonder where they are. probably in a very cold basement somewhere.

    Maybe restoring a low pressure (under 6 ounces), would stop the leakage.—NBC
