Vac table PVC flange and ball valve source?

[blackhawk]

I'm getting ready to setup a vacuum table. I'm currently laying out my piping. It seems like the consensus is to use 3" piping for the manifold and then 2" to the table.

Does anyone know where to get 2" PVC 90 degree flanges that mount to the bottom of the table? See the pic attached that I took off the Shopbot website. The only right angle flange fittings that I can find are for household central vac systems. I found some schedule 80 straight flanges at McMaster but they were pretty pricey. Anyone have a source that they could share?

Anyone used these 3" ball valves from Amazon? The ones at Home Depot are double the price and are special order. https://www.amazon.com/Inline-PVC-Ba...l%2Bvalve&th=1

Thanks!

I got everything I needed from a local plumbing supply house, price was on par with local Lowes but they had better selection of some parts like the ball valves and flanges.

check out the thread below before you use ball valves, there is a better solution. Ball valves will become problematic with repeated use. I can look tomorrow and let you know where I bought flanges.

I'm using similar ball valves on my setup and they work fine. They have a little stickiness when you first turn them. If you were flipping them open and closed hundreds of times a day I could see it getting old, but if it's only a few times a day, or even hour they're just fine for me.

Like you I ordered mine online, but I got everything else locally.

Just use a regular 90 with a nipple into the flange or a street 90 and the flange. All the pieces to build the system are stock plumbing parts.

Before you get rigid pipe, check out 2" flexible PVC. That's what I used. It's 1/10th the trouble to install and doesn't require elbows.

I'm curious why you want to use 3" ball valves? I'd think 2" would be fine. I used a 3x2x3 T to make my manifold and attached 2" ball values.

Only a few bucks more than ball valves but easier to use and should last longer.

Thanks everyone. I have settled on the 2" Valterra valves for my manifold.

I still cannot find any 2" 90 degree flanges to bolt to the underside of the table. I spent an hour searching online and went to 2 local plumbing supplies. If anyone knows where to find them, I am all ears. If I can't find any in the next day or so, I'm just going to take JMCS' suggestion and just put a street elbow into the plenum hole and seal it off with silicone.
