USAV vents?

I just got done swapping out almost all of my vents with the Hoffman 1As.  Have two left to do, one of which I need to drill out and install a bushing.



Anyway, most of the vents I pulled off say USAV on them.  A few say USAV 1A which seem to be an adjustable, yet very very slow vent even wide open.

Who is USAV?  Are these vents even worth my holding on to, or should they just go in the garbage can? 

Single pipe 392sqft system with an EG-40 rated for 325sqft and it's silent and balanced at all times.

    My local hardware store started stocking those about 8 years back so I used them on a couple of my radiators. My experience with them was not good, they started to spit after a year or two. I'd hang onto one for an emergency replacement and dump the rest.
