@K Sykes - You're a genius haha; it is definitely hitting the adjustment screw.
So now I guess I need to adjust this until the butterfly valve is as close as possible to closed without letting the valve itself dictate the maximum closure point? Also, I will need to adjust the other adjustment screw so that it will still make contact (see picture below--Yellow Arrow) but will not damage the connection to the microswitch
Thanks Again,
Alex
