Repacking Steam Rad Valves

Happy soon to be Thanksgiving all!



Question:



On my one pipe system 3 out of the 8 rad valves are leaking steam at the valve.  They need to be repacked.  Any ideas on which packing I should use before I start wandering around the plumbing supply store?



Both for the stem and the seat connection just under the stem.



Thanks for info...

    Valve packing

    Graphite impregnated string is used for replacing. What is your pressure? --NBC

    Pressure?

    NBC:



    just under 2 psi out

    0.5 psi in



    I used the string and lo and behold, no more leaking!



    Sorry it took so long for me to respond but I have been "recovering" from Thanksgiving..

    Tighten the Packing Nuts.

    I just repacked my radiator shutoff valves a few weeks ago, and found they loosened up.  I think the string settles in after a few heating cycles requiring the re-tightening of the nuts to seal the valve stem.

    Packless Valves

    How does the Dunham packless valve work (they have wood handles). I have yet to take one apart.
