in Strictly Steam
i went on a call in which there was a steam valve on a radiator that will not close and the flow of steam keeps coming,and the room overheats.it is a manual valve so i believe the internal parts are just worn out.the only information that i can get off the valve is the chicon regulator company and that's it.i have attached a picture,does anyone know if the parts to this valve are available? thanks to all

    Overheating room

    These valves, probably for a vapor steam system, we're designed for very low pressures, so have a look at it's performance when you have verified the pressure to be a couple of ounces. You will certainly need a 0-3 psi gauge (gauge store.com), and also a vaporstat, set to 6 ounces maximum cutout.

    How is the rest of the system behaving?--NBC

    Similar to Trane

    That valve looks almost identical to the one on my Trane Vaporvacuum system. It only opens  a predetermined amount, but mine will shut off. Orifices will approximate this effect. I know there were many manufacturers doing all sorts of things at that time, but you might want to check under the vapor/vaporvac or Trane sections of the lit on this site. It show the variety of valves and from that you might be able to determine if you can fix it. If you don't ,let me know as I'd love to have it.  Colleen

    Lit links

    The best reading I've found as a homeowner is under the Systems and Resources. Here are a couple of links that may prove of value:

    If you look under the Trane heating section, there's the valve just like mine and almost exactly like yours.
