        First, i must say that i thoroughly research EVERY product i buy... i like to see a return on my investment..so yes, i thought twice before forking out the money for these valves...but i'm glad i did....

        i have a 3000 heated sqft. 3floor, 120 year old home in Northern NJ. i am 12 years in house with 9 years using Danfoss thermostatic valves.

        i have 14 radiators on 3floors...5(1stfloor) 6(2nd floor) & 3(3rd floor).
        11 of these radiators have Danfoss Valves..

        i swear by these valves.... yes i know they aren't "cheap",but trust me, you will recover your money because you will see a dramatic decrease in your utility bill. it allows you to control heat in unused rooms. it can be 20degrees outside and my boiler is only pushing steam into a few of my rads.. NOT all 14 of them.

        MY ONLY WARNING is this: the Danfoss Valve is NOT meant to be inside an enclosure(radiator cover)...it will cause a false temp reading. Sooo, if you use a Danfoss valve make sure you have it exposed so it can read the ROOM TEMP, not the temp inside the rad enclosure.

        if you have steam heat, i highly recommend these valves... it will keep you from heating rooms you dont use or allow each person to keep the room as warm or cold as he wants...

        Don't let the cost scare you from buying them... Try ONE valve...trust me, you will buy more...

              The three-part Danfoss steam valve, operator, and vent control the "too hot" and "too cold" radiator complaints. Easy to install.

              Great way to cool down hot rooms

                    Comments about Thermostatic Rad Valve w/ Vac Breaker (1 Pipe Steam):

                    I have a two story colonial with 3 bedrooms that vary greatly in size. I originally used vari-valves to try to control the heat and they worked, but the rooms always still received heat during each boiler cycle.

                    Since i changed to this product i see a huge difference. My wife likes to sleep in a cold room, so we keep the dial turned way down. It's better than turning the valve off complately because if the temp drops below 64, the heat will come on in the next cycle.

                    It works great too for my sons small bedroom, where the ambient heat from downstairs keeps his room warm enough on it's own.

                    Overall, it seems a bit pricey per room, but in the long run, the comfort is worth it. We're probably saving a bit to on heating costs since my wife no longer opens the windows in the middle of the night.

                          The polar votrex was kicking my butt this winter causing my 2nd floor steam rads to run hot as heck. installed a couple of thermostatic air vents with operators that have remote sensors (the rads have covers) & the 2nd floor temps are now the same as the 1st floor. These units are long so you have to make accommodations if you have covers on your radiators like I do. Worth every penny & then some.

                                                              Thanks to the vacuum breaker, this valve finally stopped my one pipe steam radiator from spitting. Works fine.
                                                              You also need the direct mount operator and steam air vent. Assembly is very easy.

I tried Honeywell but they lack a vacuum breaker so the radiators would accumulate water and spit it from the vents. I tried Macon and while they have a vacuum breaker, the low pressure of my system couldn't activate it so the result was again radiators accumulating water and spitting it from the vents.

                                                                    Then I tried these Danfoss TRV's. They work perfect. The vacuum breaker works perfectly and is activated with only an infinitesimal amount of vacuum pressure. Our radiators are staying dry, vents aren't spitting water, and all bedrooms are staying cool just like I wanted.

                                                                    I could have saved myself hundreds of dollars by choosing these TRV's in the first place.

                                                                      I have a radiator that is recessed in the wall and I have about 3" clearance from the end of the radiator to the edge of the wall. Can I get this valve to work by turning the Valve 90 deg. from the radiator? Is there a part made specifically for such an application? I would also need a remote sensor since I will be installing a radiator cover. (It is a 1-pipe system)
                                                                      Any help would be appreciated.

I used a street ell (male thread one end, female the other) to mount the valve, and a remote sensor and thermostat dial. Worked fine.

I had to use it on 3 radiators in my home BUT you need a minimum clearance of 41/2 inches from the end of the radiator to the wall for it to work. You might cobble together something out of steel pipe but understand that the entire TRV valve assembly will then project outward of the radiator. I'll try attaching a picture of the Danfoss assembly to this reply. I'm not certain the "system", (PexSupply) will allow it. ...............

I have a feeling the radiator is angled slightly wrong and the water is not draining back into the radiator. Is there a 45 degree elbow or something that I can install to fix this?

You write that you think the water might not be draining from the radiator....have you checked the level of the radiator and does it pitch towards the steam supply pipe allowing condensate to drain properly? Is the supply valve fully open? If the supply valve on the steam supply pipe is not fully open the radiator will not work correctly. Read about one-pipe steam systems at <HeatingHelp.com>.

As soon as I replaced the bleeder valve with a new one, the banging stopped. I am assuming that the valve was clogged and not allowing air in so the water could drain back down to the boiler.

This valve's operation is pretty simple - it is either open to the vent or closed, at which point it acts like a check valve allowing air into the radiator but not out of it. When it's open, it just relies on the air vent to function by letting air but not steam to vent. Any valve should work with it as long as it is the correct orientation.

It would be extremely helpful if the product listing gave that numbers of the other parts that are needed for specific applications (e.g. 1 pipe steam). You might consider bundling the three parts that one needs for a thermostatic assembly together under one product number.

                                                                      My understanding is that the gray control pictured is a manual control, and to implement a thermostatic valve function for 1 pipe steam, one also needs the Danfoss Direct Mount Operator (013GB8250) and a vertical air valve (e.g. Danfoss 013L8011). I imagine that one takes off the gray manual control knob and replaces it with the white thermostatic operator, and one removes the brass plug on top and inserts the air valve. Is this correct?

                                                                      It seems that all of the thermostatic steam air valve controls have these three parts. Are there any alternatives available that combine the operator and steam valve?

Steve, you got it right with one clarification. The "gray control" on the valve is a cover for a little pin which when pushed in closes the valve. The direct mount operator is a required piece (the valve is always closed without it), and it does snap in place where the gray cover had been. And as you say, you need all three pieces (about$124 total) for the system to work. Installation is 15 minutes: screw in the valve in place of your present steam release valve, snap on the Direct Mount Operator after removing gray cover, and put the vertical air valve on top of the valve. The direct mount operator has a dial knob to choose the temperature at which the valve closes stopping any further heating. Good luck!!! . . . I love this product so far (1 month of heating season).
