New radiator valves

Luv'nsteam

What is the proper name of the type of valves used to control the on/off flow of steam and condensate into a one-pipe steam radiator? 



Are these the correct kind?

link no worky

Mike -- that link you posted does not work .. but I think you *may* be looking for Thermostatic radiator Valves (TRVs) .. [url=http://www.google.com/search?q=thermostatic+radiator+valve]http://www.google.com/search?q=thermostatic+radiator+valve .. I believe that Dan Foss or tunstall makes ones which are suitable for 1-pipe .. but you need to get the ones specifically suitable for 1-pipe and the valve must go on the vent-end of the radiator .. not at the floor valve.



I may have also read into your post too much and you are simply looking for something like this .. http://www.pexsupply.com/Matco-Norca-BARVY-1250-1-1-4-FIP-x-Male-Union-Steam-Angle-Radiator-Valve-4649000-p

Radiator supply valves

Jpf,



Don't know why the link failed, but when I clicked it, I did go to the menu of Hammond valves.  On the left side choose "Plumbing and Heating Valves".   In the next menu on the right, choose "Search Product by Type" and choose "Plumbing Radiator Valve" then choose "Show Selection."



 At any rate, the link you provided is pretty much what I was looking for.  I was wondering what the actual name for this style of valve is (gate, globe, butterfly, etc?).



Also, what is the material one-pipe steam radiator supply valves are made of (bronze, brass, steel, iron)?



And when installing a valve that is horizontal into the radiator from a riser that goes up one more floor, other than providing the correct pitch so the radiator drains, are there any other rules I need to utilize to make sure my installation is correct?



Thank you,



Mike

Supply Valves - Steam vs Water Valves

Mike - Just make sure that the model valve you looking at is actually specified to work with steam. I've run across valves that were outwardly physically identical to steam valves but won't work well with steam (HW only).  The innards are slightly different.
