Hilde I bought a Swagelok B-1VS4. Anybody using it? Pros, Cons?

Bettatail was just saying that one valve was better than the other. Better meaning more control over how you adjust your flow rate (bubble count).

Mathman I've got plenty of white cords. Went with black and white in case I ever need to deferentiate

Looking good! Find another white cord. H3 metering valves are a keeper.

Hilde Read at a thread that a needle valve 1300 series a 1 degree needle is better than a 3 degree needle.

What does this mean?

* = 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:
4- 1/4"
2- 1/8"
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.

FlyingHellFish 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.

I thought 6000 PSI was good. Thought that the higher the better. I don't understand these valves and can't find any info to make sense of the numbers. Numbers such as for Swagelok 20 series needle valve, soft seat stem. Part number SS(B)-20R* Orifice: 0.08" Cv: 0.09 (at 2.5 turn full open)

Cheap (???) Chinese needle valve. I don't know of any opinions good or bad on them.. Personally stick w/ "name brand".
A Fabco is good enough w/out getting too fancy.
