Needle Valve - Swagelok S Series not cutting it!

I put together a DIY CO2 regulator setup that I'm having trouble with. I'm using a Victor regulator, and a Swagelok S series (SS-SS2-A to be exact) valve to meter the CO2 flow.

With the regulator set at 10psi, which is as low as I can get it, I'm getting more bubbles than I want even with the valve completely closed.

Has anyone else used S series valves in this kind of setup? Does it sound like I've got a defective part, or the wrong part for the job?
