One Pipe Vacuum System

I just bought a house and noticed that there is a Hoffman No 16 vacuum valve on the main but the radiators have newer conventional air vents. Is it possible to convert the original vacuum system to a non-vacuum system with no loss of efficiency of do I need to buy all new vacuum vents for the radiators?

    As far as I know vacuum vents are no longer sold, so yes it basically is already converted

    If it is a one pipe system, it is very unlikely it was ever a Vacuum system.
