I use them exclusively.
Gotcha! I was confused when I read this article.http://byo.com/stories/projects-and-...ate-in-the-keg
"To calibrate the adjustable pressure relief valve, you only need to monitor the pressure gauge. When it slightly exceeds your desired carbonation pressure (I generally shoot for 14 PSI) turn the top adjuster counter clockwise until pressure just starts to bleed off. Watch the gauge and when 14 PSI is indicated turn the adjuster back in (clockwise) until the pressure stops escaping.
After 4 or 5 days, turn the relief valve adjuster back in (clockwise) 1/2 turn and monitor the gauge for another day. If the pressure does not increase, you know that all secondary fermentation has ceased and the proper carbonation level has been retained.
An added bonus is that you need not transfer your beer again. It is well carbonated and ready to chill. Your secondary fermenter also doubles as your serving tank. Cheers!"
I thought the article was describing calibrating the keg pressure each time. I didn't know you could set it and forget it!
I looked up the valve, it ain't cheap! $16.82http://www.drillspot.com/products/47...e_Relief_Valve
