    Need help trying to identify old steam valve

    I either need to replace parts for these valves or replace the entire valves because they are leaking. They were installed in 1937 and I can't find any information on the manufacturer, and can't identify from the logo stamped on the side (pictured).

    Also, is this valve thermostatic?

    Thanks!

    C. A. D. C. O. What a logo

    Plain english would have been easier, no?

    C. A. Dunham, now sold as MEPCO. Statesupply.com carries their vavles, maybe they can help you with the innards and knobs.

    Seems to me this is a packless valve, the springy separator inside might be leaky, missing or just a little unseated. For a model no, perhaps a 740. mepcollc.com

    oh forgot to mention you can probably get an all purpose replacement handle from a hardware store that might work.
