old supply valves on 2 pipe systems

Hollis

This house has the old supply valves on the two pipe system that has a wooden handle and a pointer that says 'open" and "shut" However they don't seem to respond to much,..a few were stuck and with some tapping back and forth they have loosened up. but it looks like despite it moving, the radiators stay full on. I'm guessing that they are internally stuck? (although it  "sounds" like things slide inside them like a sliding  gateway.)

Guessing that they just need to come off and replaced with new valves?  (i hoped to get them functioning as I like the antiquity of them.)

Before you replace them

take some pics of a valve up close, and a couple radiators. Some of these valves had orifices in them that kept steam from reaching the return lines.



Have you found any manufacturer's name on these valves?

I'll take them...

If you don't want them or can't fix them, please contact me as I would like them. I'm trying to replace the ones in my house that were removed.Thank you.
