CarbonDoser® Precision Check Valve”Corrosion Resistant” (4 psi CRP)
After years of experience with CO2systems, we discovered why consistent “bubble counts” are, most of the time, impossible.Here’s why: ALL checkvalves, even expensive ones, have a “high crp” or “crack pressure” rating (the pressure at which they actually release) and/or a very inconsistent “crp” pressure” rating. We actually took a “caliper” and measured the CO2tubing at different times and what we found is this: The tubing is actually a “long balloon”… When pressure builds in the tubing (because of a high crp rating of the CV) CO2is “stored up” in the tubing, until the CV opens. Then it releases, then it build up again, and more or less “cycles”. What you experience is a very inconsistent bubble count.
