Buzzing Regulator

[kingnothing395]

I've been bottle conditioning for years, and recently started kegging my homebrew. Today, I kegged my second batch. I left the CO2 bottle in the refrigerator after my first batch. When I opened the regulator to let gas into the corny keg, it registered 2-3 pounds and then started buzzing. The needle started vibrating. I shut it off, and turned off the valve at the bottle. I opened the regulator again, and it did not buzz. So I opened the valve on top of the bottle, and then proceeded to slowly open the regulator. It got up to around 10 lbs and started buzzing again. So I backed it off, and slowly opened it again. Extremely slowly, in small intervals over a period of 15-20 minutes, I opened it all the way up to 20 lbs. Everything seems fine. Am I okay, or is my new regulator defective or about to explode and ruin my beer?

Thank you for your time!

Odds are you were listening to a spring-loaded-ball backflow-preventer (aka "check valve") integrated into the shut-off valve rattling in its bore due to gas passing through.

I get that on some of my regulators (and certain valves on my manifolds) if there's a large volume of CO2 passing through. Once the pressure gets close to equalized the rattling ceases...

Cheers!

Thanks day_trippr! So there's no danger to my beer?

Lol! No, zero threat there.
There are dozens of things one might worry about, but this isn't one of them

Cheers!

you think you're scared of buzzing now? ask anyone that's lost a co2 tank to a leak, then you'll really be scared!

as long as it doesn't last, it's normal....mine buzzes all the time when i pour the first couple glasses off a full keg.....as long as it isn't gently weeping all the time, i'm ok with it..... and congrats on the move to kegging!
