  • Old heater control valve rebuild

    I was about to go to a NAPA store to buy a heater control valve.
    Then I found a 1940's vintage one.
    I was intrigued by the possibility of rebuilding it.
    I sandblasted the outside and cleaned out the inside.
    The plunger is nice looking brass.
    The packing was asbestos rope, I think.
    I happened to have the same material, from where I don't know.
    I twisted several strands around the plunger where the old sealer was.
    Then I reassembled the valve.

    Is this the right procedure to renew this old water valve?
    Is it worth bothering with it?
    If yes, then I would like to use it on the 37 CE I am working on.

    If you can make it work, go for it. I think the packing was graphited cord of some kind, not necessarily asbestos. Industrial plumbing supplier should have valve packing.

    My big complaint about those old hex-body valves that Stude used is the monkey-motion linkage that simply can't apply enough force to move the plunger fully onto its seat.
