The only non-electric control valve that is metered and automatic is form
Kinetico but... I have many control valves that are electric and have
sealed
covers meant for outside use. And I would suggest them over non-electric
for
a number of reasons in addition to the price of the control.

I can tell you the volume of resin the tank can hold if you tell me how
tall
the tank is and the diameter. I would also need to know what type tank;
very
flat and smooth plastic or plastic but stranded fiberglass.

The unit is a 1 piece system with the resin tank enclosed in the brine tank.
Because the tank is confined within the brine tank, I got as accurate of
measurements as possible as it sits in the back of my truck.
The tank appears to be 37 inches tall with a diameter of 11 inches. It is
stranded fiberglass.

I appreciate the input on the control valve so far as the non electric.
What valve do you recommend for this resin tank?

Thanks again
