Ballvalve to control bubbles on Ca Reactor?

[DrHarryLopez]

I setup my Deltec PF601 Ca Reactor. The control valve of the CO2 release is a ball valve type. This is the worst valve to control any type of flow! Control comes with micro adjustment, and when it is needed for bubble count finer adjustments is required.

Jarrett bought this digital controller and raves about it
