Option# 1) http://www.chnv.com.cn/product/n2-needle-valve/ = $60.00 shipped New.
Option#2) http://www.swagelok.com/search/find_products_home.aspx?part=SS-4MA-MH
= $35.00 + 18.00 for shipping New.

Lastly used Swagelok 6000psi SS316 part# 4GUF4 $16.00

please help me figure out what option is the best bang for my buck and of good quality.
Thanks to all who read this...

I'm very happy with the Fabco NV-55, bought new from Fabco. I also am satisfied with their NV-55-18. Both are very good reliable valves with smooth movement that does not slip. Same internal parts in each but the difference is in the ports(openings) in the valve. The NV-55 is nice and small using the 10-32 fitting which some find too small. But the NV-55-18 is too large and heavy for me to like just for using 1/8" solid plumbing. I like seperating things on tubing. I find it easier to place parts where I want them and where they are less likely to get broken when I'm changing tanks. I made a small bracket to get the NV-55 out of the way and where I can get to it easy.

If your measuring by BPS or using a controller do you really need dual gauges? There are a handful of aquarium specific valves in that range with a single gauge.

The needle valve is labeled Number 2 in the picture.
I think you may be confusing needle valves which are the question with regulator and gauges?? But on the need for two gauges, I would not want to use a single gauge reg as one tells me the output to the equipment and the other tells me the tank pressure. Once the liquid is used out of the tank, the tank pressure lets me know how close to bottom I'm getting. I feel I need both.

Been looking for this Fabco NV 55 in Canada with zero luck.. Any ideas as to find a place that will ship to Canada? I will 100% use this needle valve if im lucky enough to find one.

You'll have to try it and let us know what you think. I don't think any of us have used that one yet.

Here is the model# 316-n24-afn4 it came from CHNV.com
This thing is pretty heavy too, did not know it was going to be this big lol
I will try this out but caint for a little while as I still require a working regulator...
A closer look at my used Victor shows that 1 guage case is busted and the co2 cylinder On/Off valve needs to be replaced. Any idea as to where to buy a 316SS C02 cylinder stem valve??

Gauges can be replaced cheaply.

I'm not sure what you mean by the CO2 cylinder on/off valve. Are you referring to the valve on the CO2 cylinder? This is not part of the regulator.

However, if you are talking about a separate on/off valve (on the output side of the regulator), then it is not needed.

It then seems that you are looking to replace the CGA320 nut and nipple, and not the CO2 on/off valve...

I'm just not quite sure what you are asking.

[QOUTE= Are you referring to the valve on the CO2 cylinder? This is not part of the regulator.[/QUOTE]

So this is the on/off valve on the CO2 cylinder?

If so, I'm not sure whether it is directly replaceable by an end user. I would advise you to take it to a welding store (or wherever you purchased your cylinder) to get it looked at.

The last thing you want is to replace it improperly and then have a fully pressurized CO2 cylinder...
