All of my local stores only carry 3/4 and 1 inch valves, would like to replace in the future with a larger valve
Originally I wanted this to launch flour over a large area, velocity doesn't matter to me in this purpose
I fixed the sealing problem by adding a ball valve between the chamber and the sprinkler valve (it also acts as a safety) and adding epoxy to the areas referenced by dewey-1

Thanks everyone for all the advice, I should hopefully have pics by the weekend

if you wanna go bigger and more power, id suggest a dust collector valve, they are a lil more pricy but def worth it,,
