Cold radiator

Looking for experienced advice:



Cold, two-pipe steam radiator next to outer wall. Trap new in 2009, wet condensate in trap and draining. Trap is open.



Steam enters supply valve but doesn't seem to be migrating into radiator. I even loosened the trap cover just enough to allow air to escape when steam came up; I got a 'hisss' but steam did not fill the radiator. First section gets luke-warm.



Supply valve says open. Any ideas before I detach the supply valve to inspect?

    Steam

    How does the supply run out look? Proper pitch? No sags?

    Valve inspection

    You may see all you need to see by unscrewing the bonnet. Maybe the disk has fallen off the valve stem.

    There may also be an orifice in between the valve, and spud, which has become plugged.--NBC

    Got it!

    While I was tinkering around, I tightened a hex nut that had come loose over time on top of the supply valve. I didn't think anything of it, cleaned up and left the house for a while. When I came home, the radiator was hot! The nut must have pulled up the disk. (I'm no plumber, but that's my theory).



    Thanks for your help!
