Tom King Posted July 13, 2022 Report Posted July 13, 2022 I just saw one in use on another forums. I guess they've gotten cheaper since I last looked at big ball valves. https://www.amazon.com/Midline-Valve-T-Handle-Connections-482T400/dp/B08CX6P23Q/ref=asc_df_B08CX6P23Q/?tag=hyprod-20&linkCode=df0&hvadid=532543771405&hvpos=&hvnetw=g&hvrand=644995830375085582&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9009793&hvtargid=pla-1440690184254&th=1 Quote
Ronn W Posted July 13, 2022 Report Posted July 13, 2022 Doesn't the interior of ball valve have partial obstructions to air flow? Quote
Tom King Posted July 13, 2022 Author Report Posted July 13, 2022 They're the same open diameter as the pipe with no leakage to the outside. A static grounding wire inside wouldn't work though. Quote
BonPacific Posted July 13, 2022 Report Posted July 13, 2022 Over $100 for a 6", $45 for a 4" still seems pretty dear. 1 Quote
Tom King Posted July 13, 2022 Author Report Posted July 13, 2022 Yes, I didn't even look at the prices, but said they must be cheaper than they used to be for someone to use them as blast gates. Maybe he ran up on a deal somewhere. Seems like they would work really well though. He did have a 25" spiral head planer using it, so I guess compared to the price of the planer, it wasn't much. I was wondering about a 6" pipe for such a big planer, but I didn't say anything. Quote
