    I am looking for a god check valve to install in a 2" vacuum conveying line. The less restriction the better.

    Please if anyone have an idea, let me know.

    Nothing really works that well except for some flapper type - most with rubber hinges that break off - can't suggest good one.
    I've used Mission Duo-chek or Daniel Chexter - butterfly types - restrict flow & can plug if lump gets to them.
