Corny Keg / regulator question

[ChrisPDuck]

Making the jump from the cheap plastic kegs to corny kegs and have 3 kegs and a regulator etc on the way. I've done a lot of reading as I fancy trying force carbonating.
One thing I can't find is if there is a 1 way valve anywhere in the CO2 route? Either in the ball valve, grey quick disconnect or in the regulator itself?
I'm really trying to understand 2 things if I set to say 10PSI but the keg gets warmer would the keg raise to say 15PSI or would it push back into the CO2 tank and so stay at 10PSI? If it does raise to 15PSI would the 2nd gauge indicate 15 (the keg pressure) or show 10 (the pressure set on the regular)

There is not any one way valve up to the regulator secondary pressure gauge. There is to the main cylinder that is at a much higher pressure.

If the keg pressure rises it will push back to the secondary gauge but not into the cylinder itself, whether the pressure drops or not will depend on the volume of the gas line. This depends on whether you have any additional shut off valves between the keg and the regulator.
If the secondary regulator is directly connected to the keg then it will show keg pressure which may or may not be greater or less than the regulator setting. If the cylinder is open then it should not be less than the set pressure but may be more.

Just a warning,,,, Double check when you connect.
Gas goes in the 'in' beer comes out the out.

If you keg condition, it will mix your nicely settling trub if you get it wrong.
Yup, been there done that
I still use bottles for my brew samples, but it is the best move I have made to my lovely cornie kegs!!!:thumb:

Yep..! What Druncan says +1. Corny's are pricey but perfect for carbing & storage. Mostly I only use bottles for what won't fit in the Corny's.
Clear beer going into your keg will stay clear when you carb (...usually...) :whistle:

The regulator is effectively a one-way valve. If the keg pressurises above the set pressure it slams the regulator shut and no more gas issues from the cylinder. The second gauge (low-pressure gauge) will record the keg's pressure not the "set" pressure.

There are exceptions where the regulator vents excess pressure on the low-pressure side, but believe me, you don't wont to go there however logical it sounds (these are "relieving" regulators).

Cheers all, got them for under £40 a keg and couldn't resist at that price.
Ended up significanty more when I added on the connectors, hoses, taps etc but man maths still says it was a bargain!
