That might be just a gauge and a valve you have to open or close manually. Austin Homebrew Supply sells the same piece (http://www.austinhomebrew.com/produc...ducts_id=10397
) and they're a bit more descriptive, but I'm not sure. If it's an adjustable pressure relief valve, the price is definitely right.

I'm totally busted. I never followed through in this thread, though I did make a spunding valve and (after moving cross-state, new job, new brewing setup, etc) am now fermenting my first batch of homebrew in a 5 gallon corny keg.
Pics, cause it is happening (though only crappy iPhone pics, cause I worked overnight)-
That's my fermentation fridge, as well as the place I store the rest of the brewing gear. More on that (chiefly my Reflectix and Line-X coated e-Kettle) another time.
The spunding valve in situ, though it's sorta hard to tell in the picture.
Better shot of the spunding valve itself.
I used about 4 feet of clear line to be able to tell if anything is escaping the keg and to try to capture it if it does. First batch, pretty darn full keg, nothing but some vapor in the line.
McMaster parts list-
4089K12 Multipurpose Gauge +/-2% Mid-Scale Accuracy, 2" Dial, 1/4" NPT Male Bottom, 0 - 30 PSI 8.52
4429K223 Low-Pressure Brass Threaded Pipe Fitting, 1/4" X 1/8" X 1/4" Pipe Size, Inline Reducing Tee 9.89
9171K212 Precision High-Pressure Brass Thread Pipe Fitting, 1/8" X 1/8" Pipe Size, Hex Nipple, 5600 PSI, 1-1/16" L 3.58
99045K44 Adjustable Pressure-Maintaining Plastic Relief Valve, 1/8 NPT Female, 0.5-30 PSI 31.64
50675K162 Brass 37 Degree Flared Tube Fitting, Adapter for 1/4" Tube OD X 1/4" NPT Male Pipe 2.12
This could definitely be done more cheaply, but I've really liked how this worked out. It's very compact. The device just sits on top of the keg. I'm just about 10 days into this fermentation.
A really slick project would be to mount it outside the fridge itself (pass through the door/top as in a kegerator) and you could monitor fermentation without ever opening the door of the fridge. Tighten the valve a bit, the pressure should rise over a few hours. Doesn't happen? Fermentation isn't happening.
