I own and operate a 36 unit apartment building built in 1926 with an original Warren Webster two-pipe steam system. About 25 years ago, my father and I performed a lot of building envelope upgrades as well as improvements to the steam system.
One of the most valuable additions was that of Bell & Gossett Thermomate Thermostatic Control Valves which really did a great job helping balance the system. However, within the last couple of years, the rubber washers started to deteriorate to the point of breaking off and becoming lodged in the valve body causing 'no heat' situations gradually throughout the building. As you can imagine, our initial investment in comfort and efficiency has worn out it's useful life. (I suppose 20 years is pretty good...)
However, it seems that Bell & Gossett (now a Xylem brand?) no longer makes parts for these TCVs? Before I go spending about $7k (parts alone) on a replacement (Danfoss, I've heard is the best?) I wanted to reach out, here on the Wall and make sure I cant find replacement parts. I checked with the local Bell & Gossett distributor and they indicated that the product is no longer made. However, I ran across an article that states the company was re-introducing the valves with new actuators as recent as 2013.

If anyone has any knowledge on these wonderful valves, I would appreciate it.
