After years of experience with CO2 systems, 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 COtubing 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 inconsistent bubble count.

Another problem that been a major issue is "water corrosion" "mineral buildup" (even worse: saltwater corrosion!)
No checkvalve that we have used or tested in the past seems to last very long when used with saltwater. (even stainless steel springs/check balls corrode)

This Checkvalve is custom manufactured to our exact specifications.
It is specifically made for us, with a "ball" that won't corrode and a spring material that it more corrosion resistant than stainless steel.(The actual materials used are proprietary)

- 4 lbs crack pressure (any less is not enough to prevent from sticking open)
- Made with a spring that is more corrosion resistant than stainless steel!
- Made with a check ball that is more corrosion resistant than stainless steel!
- Units are not "glued" when manufactured which allows disassembly for cleaning.
- Do not confuse with similar looking cv's. These cost much more to manufacture... there is a difference!
