Hi. Is there  a comprehensive listing of radiator air vent drop away pressures? Do the manufacturers publish this info? Thanks.

    Not that I know of. I don't recall leaving a system with the pressure high enough that it would be a consideration.

    I can only speak from one experience with one Gorton #2. It wouldn't reopen after it had been subject to about 4 psi until I tapped it gently. Then it did.
