    Three way ball valve

    Hello good people.
    I'm trying to join two chest freezers to one compressor. The capacity of the compressor can only support 1 freezer. I need a "3/4 inch three way ball valve" between the freezers and the compressor so that I can alternate it's operations manually.

    Unfortunately, the 3way valve I saw wasn't 3/4" all through. The fitting ends are 3/4" but the inner diameter is reduced and becomes narrow inside.
    See picture attached.

    Please, how can I get a true 3/4" brass 3 way ball valve?
    Thanks.

    You do know that chest freezers are critically charged systems that operate on a minuscule amount of refrigerant, right? You also know that that isn't a refrigeration ball valve, right?

    Unless your name rhymes with "Noodlehead Bikey", I give this about a zero percent chance of working.

    What you're looking for is a full-ported, three-way refrigeration ball valve...like this:

    How big are these chest freezers? They require a 3/4'' ball valve?

    The OP has a previous thread about his "chest freezer": https://hvac-talk.com/vbb/showthread...-Refrigeration

    It's 15 ft x 15 ft x 5 ft high.

    No, I've never seen one either, but I noticed that Meuller was making them a while back when someone else on here was looking for 3-way valves. I seem to recall seeing a Sporlan modulating three-way valve in their literature recently too.

    Exactly! Thanks sir.
    I studied electrical but I fall in love with refrigeration. It's interesting.
    I just like to put my ideas in practice.
    U are always ahead.

    Sporlan makes a 3 way that is activated by a solenoid.
