The valve needs to be centered in the channel. The channel needs to be centered between the beads.
Diamondback got this wrong on their Blanchard rims in the late-2010s and it caused seating problems for the tires. They offset the channel to match the spoke drilling, and so there was no "shelf" on the narrow side between the channel and the side wall to guide the bead to its seat. When you hit it with the compressor the wide side would seat and the narrow side would flutter. I don't know if they have changed it since then.
