"THE BEST" Check Valve (medical grade)
"THE BEST" Check Valve (medical grade)(.017 psi CRP)
After years of experience with Co2 systems, we finally discovered why consistant "bubble counts" are, most of the time, impossible. Here's why: ALL checkvalves, even expensive ones, have a "high crp pressure" or "crack pressure" rating (the pressure at which they actually release) and/or a very inconsistant "crp" pressurre" rating. We actually took a "caliper" and measured the Co2 tubing 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) Co2 is "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 inconsistant bubble count. This Checkvalve is "medical grade" (imported from Germany) and the best CV available.
