I'm using 2.5" dust collection in my small shop and I liked the idea of using some PVC ball valves for blast gates -- I just like the clean look of them and the sealed fitting versus the plastic or aluminum blast gates.

However, when I checked them out at the big box store, I found every single one they had in stock virtually impossible to open/close -- they were far too stiff.
Does anyone here use them? Thoughts?
