$10NL 6max: Flop Top 2pair 3way -What action do I take?

[Draidin]

Players are passive and are showing down top connectors when in pots. AQ AK KQ etc. players are not betting flops unless they connect. I have only shown down ONE hand with a K high flush when I first sat down. Also have taken down several pots since then uncontested.
Action:
I flop top in two in a three way pot. How can I extract most value?
