B = Brass
(The parentheses are telling you it will be SS or B)
20 = the model (not sure what the R denotes)
* = Connection style/size. The asterisk will be a combination of a letter and a number.
S- tube fitting
F- female connection
A number will follow the S or F. It denotes the size of the connection.
The only ones that really concern us are:
So for instance, SS-21RS4 would be a stainless 21 series with a 1/4" tube connection. B-31RF2 would be a brass 31 series with a 1/8" female connection. Keep in mind that is only the breakdown for that type of part number.

Making sense of the numbers:
Small Cv = This tells you the rate of flow for the valve....
Small Orifice = The size of the hole that the media flows through....
Handle turns = The amount of turns the valve has....
*The handle itself* = Easier to turn, torque, turn counter
No worries Hilde, we all have to start somewhere.

A Fabco is good enough w/out getting too fancy.
Hoke 1300's are rated at 3000psi brass 5000psi stainless steel

A hint is that the needle valve can work at 6000 PSI, which would indicate that it is not really precise enough for our purposes. Also, 6000 PSI seems to be ridiculous; are you sure it was not 60 PSI?

I'm using a Clippard MNV-4 needle valve on my Atomic Co2 regulator that has a fixed working PSI of around 30psi (that's what it levels out to after a while). I can't seem to reliably adjust my Bubbles down to 1 bps. After a few days, I have to re-adjust the needle valve. I'm only about 1/8 to 1/4 turn out from Fully closed. Interestingly, adjusting the needle valve requires me to crank it open a bit, close it, and crank it open again. Going back to about the same needle position.
I was thinking of switching to a fabco nv55 but based on specs, It might be the same. Am I doing something wrong? or is there something out there that will not fluctuate as much. I've run other MNV-4 on about 20-30psi, but at a faster bubbles per seconds on larger tanks, seemed fine, I'm currently using this setup on a nano, about 3.5 gallons with an external reactor, so I don't need that many BPS. Any recommendations that doesn't exceed $60? and is readily available?

Which reminds me, I am overdue on my PM to bettatail.

What metering valve is it? I got a friend who needs one for his build, the 2 Hoke I brought never came (you guys know where that thread is) so now I'm stuck here trying to get my friend a metering valve so he won't end up with a fabco....
If it's the Parker H3 and below.... omg!

|AlanLe||the h0. it's too expensive. 1/8 tube fitting. all we are doing is raising the price. seller will profit.|
|07-19-2014 07:04 AM|
caution! something similar appear!
