I've seen builds where the stands are tall enough that folks just slide the corny under the dump valve, and pour in from there, and other folks (like hamilton there) have a racking arm? I was kinda thinking that since the conical will be directing all the trub to where the racking arm sits in the conical, you had to be able to rotate it up and out of the way until after you dump trub/yeast? (Be nice to be able to push with CO2, but I imagine trying to pressurize these will result in a loud bang and a serious mess!)
thats what i thought about pressurizing until a saw a thread on here where guys were pressurizing normal fermenters... but intentionally not making them air tight. by letting them leak slowly on purpose they were able to still maintain enough pressure to rack, while obviously pissing some co2 into the air...

Can you use Carbon Steel Ball valves for brewing?
I'd like to buy some because they are cheaper than SS, but if they will not work i'll pass on them!

Nope, carbon steel rusts. Bad scene using that to contain your precious wort.

the valves in the link he posted will work, just not the previous question about the carbon, correct?

Yep, those are stainless, and that's all good.

Here is a large stainless conical that I have been working on and off for about a year. Just finished the stand right before Christmas. Still need a seal for the top, it is the same diameter as a 55 gal drum, so I will be ordering some EDPM seals from McMaster. I am also using a drum band clamp to seal the stainless lid. I have never been able to find a stainless band clamp, but I am still looking. All of these parts were bought at a scrapyard except for the castor wheels. The tank just sits on a rubber channel gasket on the stand. It has a racking arm attached to the top valve. You just loosen the tri clamp and rotate the arm up and down. Not sure if I will ever use it because it is so damn big. I don't have that much into it though, I got the conical tank used for $70, the lid was $15, the stand I found was already built $20, I just had to lengthen the legs, the valves were $5 each and the large thermo $5. I frequent this place often, but It took almost a year before all the parts came together. It can hold up to 30 gallons and still has about 7 inches left to the rim. I am also concerned about temperature control, I would have to build a fermentation chamber to keep it cool in the summer. I was wondering if I only filled it with 20 gallons of wort if the large headspace would be a problem. I feel it would be O.K. as long as the seal is good and the airlock bubbles, the co2 would still be on top of the beer right?

No worries even with a 5 gallon batch as Co2 is heavier than air and will make a Co2 blanket protecting your fermenting wort.
The large sealing area plus limited pressure during fermenting as well limited perssure applied to transfering to a corny, think about it before going into it too deep out of pocket.
