CO2 check valves - what are you using?

[coastbrew]

Wondering what people are using for CO2 check valves at their carb stones and CIP arms for charging head space.
We use 1/4" ball checks from GW Kent (http://www.gwkent.com/ball-check-valve.html) and haven't had great luck with them. Each seems to have a different cracking pressure and the CO2 seems to pulse and flow inconsistently through our carbonation stones when we try to trickle it in with a flow meter.

Any suggestions would be appreciated!

We just buy Taprite secondary regulators with check valves. Absolutely no issues.

duda diesel has some stainless check valves as well. they're alot cheaper, but i havent actually used them on our co2 lines, only on water lines for other little projects. no leaks, no failing with alot of use. the smaller 1/4 to 3/8 sizes were under $10 a little while ago. maybe buy one a test it out?
