        I purchased a few of these to replace the old, cruddy and clogged valves on my house radiators. My house and it's heating system are very old and the radiators are the old wide and thick type. Before I purchased this particular valve, I bought some very cheap adjustable valves. They were extremely noisy, produced steam vapor, water mist, dripped and smelled when the heat was on.

        I like these Hoffman valves because they are very quiet and they don't produce any vapor or mist. They don't click on and off like some other valves. They don't drip. They are well constructed of a heavy chrome plated steel. Also, they are adjustable so that you can regulate how fast the heat comes up on each radiator. You know how some rooms seem to heat better than others. Actually, I can get heat quicker than I did before when I had my old non-adjustable valves. The only drawback for me is that they sometimes stick closed. One tap unsticks them. I attribute that to my old heating system. In my opinion this Hoffman valve is worth the cost. I may even try getting a couple of their non adjustable valves also.

        If you have single pipe steam heat, you need these, or something that does their job. Still, I get tired of replacing them periodically at [$] bucks a pop. At least they're still made in the USA.

                    In my opinion, this is the gold standard for one-pipe steam radiator vents. Adjustable to six settings is more than adequate for most residential applications. My system is much better balanced with this vent in place and the vent was a bargain at [$]

                          I replaced all 12 in my house built in 1934. I had previously bought some chinese off-brand non-adjustable air vents. From day one, those NEVER worked right. My pipes would rattle and bang like there was a burglar with a sledge hammer in my house. After putting these on, the system is quiet, save for the occasional whistle until the vents shut down. All the rooms in my house are now warm. I'm sure I will see savings in my heating cost since the old vents never closed and were constantly venting hot steam.
                          It is probably a good idea to pick up a 1/8 npt tap prior to installing, the radiator threads in all my radiators were corroded. Quick re-tap and they fit and threaded in perfectly.

                                This product was recommended on a YouTube video. I decided to take the "you get what you pay for" advice and purchased the Hoffman Adjustable Angle Steam Radiator Air Valves from PexSupply and I'm so glad I did. Easy instructions were included and I installed 8 of them within 45 minutes. Great price and great quality. I'm sure they will last a very long time. All radiators are now working properly. PexSupply shipped them to me by the next day! I was also impressed with their customer service department.

                                                  After reading reviews, I ordered these valves for my ancient steam system. We always had hot rooms and cold rooms and VERY cold rooms.Replaced every valve and what a difference! Set them at 6 in the cold rooms farthest from heater and worked my way down the scale as the radiators got closer to the heater.This house is balanced like it has never been in the 30 years we lived here.Everyone in every room is happy and I am the hero!! Thanks again to all who recommended this product.Also a huge thanks to Pexsuppyy.com for fast service and a great price.Ordered on Sunday night,got them Tuesday. Awesome!!

                                                        Our large pre-Victorian home, constructed just after the Civil War, has many old steam radiators, and we have used Hoffman air valves for ages. I noted that the new valves were just like the reliable ones we had used for decades, and that's good. I installed them carefully with the threads taped for secure fit. And I tried my best to dial the air valves properly according to their distance for the boiler. We're ready for a cold winter now, thanks to the Hoffman air valves.

                                                              We have owned this home for twenty years and gradually the heat has been getting less and less efficient, with some radiators that stayed completely cold. I did a little research and discovered that these valves are still made and are an exact match for the ones we had. I put them on all 6 radiators just in time for the recent frosty nights and adjusted them, slow (setting 2) on the closest and fast (setting 5) on the farthest from the boiler and every single radiator got hot when I lit the boiler. I hear a faint whistle when the boiler fires now indicating that they are working and the house was much more comfortable for the recent two cold nights. Now I remember why I love steam heat, thank you PexSupply and Hoffman. If you need them, be sure to check out the six pack, well worth your while.

Steam enters the radiator, condenses into liquid water and gravity causes it to drain back down the same pipe to the boiler.
