it did the job.
I had it tee'd off my return.
If I recall I used a JG 1/4 shut off in-line before the valve. To slow down the flow first, then fine tune with the valve.
I think for what my purpose was and yours, the lack of precision is acceptable.
my flow rate was faster tho.

only thing I would be weary of with a slow drip kalk effluent is the potential for precipitate to form at the exit tubing.
