Corny Keg PRV problem
Hiya, I'm pretty new to kegging and ran into my first problem 
I was carbonating a wheat beer yesterday using the 30psi over carb method, at the time i thought it was kinda strange that I could still hear 'gurgling' after a good 10 mins, but didn't think too much of it.
Was going to try some of my beer today, and found there was no pressure in the keg, so i checked for leaks and found one near the pressure relief valve fitting. My problem is with the fitting itself.
The valve of sorts does not have any control or pulling device that would open a valve to let out the air. It looks like an aluminum nipple that sticks above the lid and has some vents in the top which show some plastic things inside, which i assume are the valve.
How do you operate this kind of valve, or take it apart? I can't really see any visible means of taking it apart or operating the valve manually...
It could also be an automatic valve that opens only when a certain max psi is reached, or a one way valve, but this seems less likely.
Sorry about the vagueness of my description, i'll see if I can find a pic or post a pic to help.
thanks!
Can you post a picture of the valve? Sounds kind of like there is a part missing.
Like this? 
My pin locks have a Valve like that.
On the underside of the lid you should see the valve. It's a gray circle with a square in the center. I carefully used a socket wrench to unscrew the valve. Took it to ace hardware and found a replacement o-ring.
The valve it type C
Awesome! That's exactly what I have! Thanks! 
There doesn't seem to be any external means to release pressure on them, so what purpose do they serve? Are they 'emergency' release pressure valves?
This is a great post. I'll know now to stay away from any lids like that if I find them.
I like having the oring valve to pull on to relieve pressure when I need too.
That lid looks like it would be a PITA!

Yes I believe they are only for emergency release. You can manually release any extra pressure by just depressing the gas in poppet.
I agree they're definitely not as good as the standard ball-lock lids, but if I found a good deal on them I'd still buy 'em.
Nicely done Quadfire. I have seven cornys, six type A, and one type B. Luckly no type C. I use the relief valves all the time for purging air, and damn it, I'm not very good at change. What would I do without a purging valve?
Yep, older coke lids.

If anyone needs the pressure relief tool (vs. opening the gas poppet - duh!), go here:
