You bet flop and you got called, so he no longer has the air portion that you hoped to fold out. That's fine. Fortunately, you are still dealing with a wide range from the BB on a very drawy board with quite a lot of hands yourself. Let's attempt to dig deeper into your question. I'll try.
The real motivation for having a turn betting range here (or any betting range) is to either have V fold his equity now or make the pot bigger in case you win. It is not so much about value and bluff before the river anymore, but rather a combination of the factors above that makes the most money.
This isn't gospel, but here is the idea broken down that may help understand why you might choose a larger sizing (aka why you want to polarize you turn betting range):
When you choose to bet K2ss on 6326hh, you do so because you may be ahead of Vs calling range (great news!, we just value bet). However, once V calls turn, he will still win some amount of the new pot on the river by improving to a better hand/even bluffing you off of yours. Because of this, you actually win more money on avg when you bet turn and V folds (great news! we just bluffed.) So, what in the world do you call a bet that is ahead of a calling range but makes more money when you get a fold??
Now, back to bet sizing. You don't have to bet K2s here, but as you said, you don't want to check turn and get bluffed off the best hand because it's too weak to call, so, you are toying with the idea that betting turn can help you realize better with this part of your range. Without getting too complex, which I may have already done, you are right in thinking that betting hands that are weak and seem to want to check can sometimes
increase equity realization/EV more than checking IP can. So what you do is polarize your betting range. To be clear that means create a polar-mixed range here with nuttier hands and weak hands that have some SDV but not enough to call a bet. That range wants to bet big for the reason in the first paragraph. That range might look like AA, 6x, other nutty hands and K2ss A3dd on the bottom. So, when you bet, say $80, you are simultaneously accomplishing what your range wants: making more in case he calls and you win the pot on the river/folding his equity and winning the pot now. When you bet $40, you make less when he calls and you win the pot on the river and less often win the pot now because he less often folds his equity.
