Sorry to resurrect this from the depths...
Just getting back into planted tanks after a long hiatus and I want to upgrade my cheap-o Clippard valve. Fleabay seems to be coming up short for metering valves that don't cost a fortune. Is anyone selling these valves on the forum I can contact? Looking for a nice quality Parker or something similar.

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?

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?
