was selling them at one point, but I'm not sure if they still do. Worth a call.

Steamhead

I can get them in the Baltimore area

don't know who makes them, but I can find out. We got a bunch of 1/2-inchers for that orifice system we're working on. We had to drill them ourselves but that's not a big deal.

orfice

Dunham / Bush (MEPCO) makes an Adjustble orfice steam radiator valve. It has an adjustable stem that prvents the valve from opening farther than the set point. Works great! your biggest problem is knowing what size orfice you want. With the D/B valve you can play with it until you find the sweet spot. Try your D/B rep or State Supply.
