I think you are misunderstanding the function of this valve. It cannot let fuel pass when the element is blocked.
This diagram makes it a bit clearer:
If you have one of these filters make sure you take a look at Maine

Yup, like Noelex already said above, the "turbo action" (or "turbine action" I believe Racor
calls it) is nothing to be excited about. In my honest opinion, it is nothing more than a marketing
gimmick to justify a higher price
on these "superdupersecretweapons" of fuel filtration.
most important factor is FILTER ELEMENT SIZE. Period. You are best served by getting the biggest unit you can fit in to your engine
room and still change the filter easily. If I recall
correct this was discussed in another thread. But anyways, nobody should think these "turbine actions" do wonders in your regular pleasure boat. Maximize your filter element size by getting the largest unit you can fit and service
insitu if you have concerns.
