They do come with a needle valve "But" They aren't that good! Lot's of people will buy a good needle valve to replace them. You can use them for a while .

Would this be a good one to get? Is it a preset one? That sounds like something I should get, one less thing for me to screw up.

I thought that was a completely separate component.
Some do and some don't come with a solenoid, needle valve and bubble counter. The JBJ and Milwaukee regulators have all these parts. The Azoo regulator has everything but the bubble counter. It has the solenoid and needle valve. Here are some links for you to see them. These links may not be the cheapest though. But, after you see what to look for, you can shop around. Reading over Darkblade48's regulator post will help you quite a bit.

There is not a picture of the V52-1-12. This is a picture of the panel mount version that also has the Vernier handle. The big nuts in the center will not be on the V52-1-12: http://idealvalve.thomasnet.com/item...ves/item-1136?

Good job!

That would be my first choice if the price is right. Heck, three years ago these Azoo regulators were going for approximately $41 + shipping.

The JBJ regulators have been discontinued at some places. I saw this when I Googled.

You can get the Ideal 52-1-12 needle valve from Ideal, Rex Griggs or SuMo. As far as I know, the V52-1-12 valve is only available from Ideal.

This one looks different to the one I linked to before plus it's cheap:

Why does it have only one dial? Is that because it is pre-set?

Which do you use? I can see how the V52-1-12 must allow for very precise control.

This isn't the model that I had in mind for you.

This is a small unit that Azoo came out with about 3 years ago. It is compact and uses its own 2 lbs
bottle. It has a single gauge and I know nothing about its needle valve. But, it is probably not a very good valve.

Notice that the complete assembly is $149 + shipping.

AZ19999 CO2 Kit (Both regulator and bottle) In Stock $149.00

There are some people using it for smaller aquariums. I've never seen it is person though. I still would not recommend it for you.

This is the Azoo model that I had in mind for you. Maybe you can find it online cheaper.

Both valves allow for very precise flow rates. Their insides are identical. Both have 22 to 24 turns from fully closed to fully open.

This micrometer handle allows you to know exactly how many of its 22 to 24 revolutions that the valve is set at plus which part of its 360 revolution that it is set at too. When ever you rotate the handle for either increasing or decreasing the flow, you know exactly how far you adjusted it. If you would ever want to go to a previous setting, you can easily find it. Also, let's say that you require a lot of CO2 for your aquarium. Sometimes the flow is so fast that you really can't count the bubble rate in your bubble counter. Many depend on their drop checker and their critters to tell them the stopping point. With the micrometer handle, you have the precision to know exactly how far out the valve is open within only a few degrees. You can easily fine tune it.

The regular handle model is cheaper, but still with precise flow control. You can follow your adjustments by counting the bubble count rather than on a micrometer handle. You can mark the adjustment knob for reference if you want to. If you would not need the precision of the micrometer handle, this would still work fine. You could always get the micrometer handle later if you want it. You can buy it separately if you wish. You just remove the stock knob with an Allen wrench and replace it with the micrometer handle. Then you "0" the handle out or you can call this "calibrating the handle."







Swagelok, Parker, Nupro and Whitey metering valves are available with a Vernier micrometer handle as well. They can come stock on these valves or you can purchase the micrometer handle kit and put it on. Here are two that I have purchased on ebay at very reduced prices.


angle flow



straight flow

That would be this one? The colors are a bit different but the structure looks the same. By "magnet valve" I take it they mean a solenoid?

Thanks for talking me through this. 15 months ago I had plastic plants, a HOB filter with activated carbon and a generic aquarium hood with 2x24" bulbs.
