My plumber came by last week to replace all my radiator valves by a brand called U.S.A.V. The model number is A850. Has anyone ever heard of this brand? I couldn’t find anything online.
So far there is no issue and the (old) steam heat system is finally quiet and balanced which I am happy with.

But there is no way to adjust how much the heat coming out of this U.S.A.V air valve. My plumber said I can adjust the heat by twist the round knob . Is it a good idea? I do have extra vari valves and Hoffman 1A that I am thinking to use. But I am afraid to do so will jeopardize the balance and harmony of the system. I was also told the knob of radiator is better to open all the way up for whatever reason I am not quite sure. Will reduce the heat out of air valve be helpful to save money on the utility bills? The radiator in the picture is located in a room on the second floor which is not frequently utilized. Any suggestions? Thank you! ![]()
