Varivalve Adjustable Angle Air Valve

Comments about Varivalve Adjustable Angle Air Valve:

We bought a number of these as replacements for our entire house with single pipe steam system. They have a wide range of adjustability and are super quiet.

It makes gurgeling noises. It seems to work fine. If you have very dry steam it may be the right choice. I would test a few of those prior of buying them in bulk.

Adjustability makes it easy to balance heat in your house from different radiators.

These move a LOT of air out of the way so steam can do it's job. I put them far from the boiler where it's harder to heat, but they would work great closer too, just adjust 'em down a bit. Easy to balance a system with the VariValve. Next I will try using 4 straight-threaded VariValves in parallel as a main return vent. A single Varivalve can move about as much air as a Gorton No. 2. I have read that when these fail they tend to fail closed, which is fine -- so far none have. My tenants like them better too.

Very satisfied. Solved my radiator problems. I installed several of these valves in an apartment building with heat distribution problems. Has a great range. On 100% open position you hear the air coming/gushing out.

I bought a box of 10 to replace all but one of the adjustable, aging, Hoffman Air valves currently installed on my home radiators. Big risk, considering I've never used Varivalve product before and just went off of the reviews written on Pexsupply's website. Plus, a local heating and plumbing supply near me wanted to charge me [$] per Air valve, for new Hoffman adjustables. So I figured for the price of three Hoffmans, I can get 10 of these, and it paid off.

I ordered every major brand of air valve for a single pipe steam system trying to find the quietest solution, and the Varivalve has proven to be the quietest. Unlike many others, the Varivalve does not have an audible clicking when the valve opens and closes. There is a slight hiss when it the radiators are filling with steam, and then a louder whooshing noise as the steam contracts. These aren't perfect by any means, but the best of those that I have tested.

I have an old house with a 1 pipe steam system. I had Hoffman 1A's on our radiators. They were always filling up with water, throwing the system out of whack and I was emptying valves every day in peak heating season. I hated steam heat. These are amazing, huge venting capacity and almost never clog up. The radiators heat faster and the boiler burns for a shorter cycle (saving $$). It takes a little time to adjust them to get even steam distribution through the house. I recommend them 100%. Change all your vents out though, if you leave a few of the Hoffman's or other vents in, those radiators will fill much slower that the others (smaller vent size). 1 valve was defective, [...]

You need to be able to adjust your valves to get the perfect balance in your steam heating system. These valves accomplish that. They are also durable and last a very long time.
