FYI on fabco, a new site for parts, TMI & what PSI?


So I'm a little miffed that Fabco just cancelled the order I placed last week. No information other than that.

I remember reading a thread somewhere regarding difficulty in getting the nv-55-18 from Fabco, but I thought (hoped) it was because they were ordering from Australia. Guess not.

So, I'm moving on. I've got all my co2 parts in hand except the metering/needle valve and check valve. My brother-in-law is an engineer, and put me onto one of the places he uses for all their parts; http://www.mcmaster.com

Awesome site, lots and lots of stuff. One might say too much. Definitely too much information! As I'm looking for a check-valve, I'm looking at where it specifies the PSI required to open the valve - some are 1psi, some 2psi, there was one that was 0.3psi, but it wasn't an optimal choice for reasons that I've forgotten (edit: it's not npt).

Anybody know at what PSI we're operating at in the x# of bubbles per second??

BPS is flow rate, regardless of pressure.

PSI is resistance to flow. I can run almost 0 PSI with an open ended air line at 100 BPS, or I can run 2 BPS to an atomic diffuser with 30 PSI. Alone, those two numbers are mutually independent.

Working pressure could range from 10 to 40 depending on the diffuser used. I try to use check valves with a cracking pressure of 1 or less. Keeps the bubble count more stable.

I should have clarified - my co2 will be going into an inline reactor... a fairly low-resistance situation (not like I'm pushing it to a diffuser that's a foot underwater or anything).

for all I know, the reactor might actually create a small suction in the airline - just hoping to glean some knowledge from those with a similar setup, instead of getting a check valve that's gonna make the pressure build before releasing several bubbles at once.

Hah - funny follow-up to my post here:

3 days after I got that curt email from Fabco that my order was cancelled, I got another email that my order was placed again and also shipped!

Too bad that during those 3 days I had purchased an Ideal needle valve.

I understand that Fabco is more of a commercial supplier, and fine-tuned customer oriented retail sales is not their strong suit, but I'm still left pretty irritated. But, as is often the case, there may be a plan in the stars. Maybe this will serve as a good backup one day when the Ideal valve fails.

*sigh*

I would just e-mail them again, saying that you want a refund issued, with your explanation above.

They should not have charged your credit card in that manner anyway.

You're right, I should be due a refund if I so choose. But then I'd have to pay return shipping, and box it back up, and watch my credit card for the return balance, blah blah blah.

I'm just going with the flow on this one. Without sounding like too much of a hippy, I can't help but suspect that when odd things like this happen it's part of a bigger plan. Maybe my current valve will fail, maybe I'll sell it to a fellow hobbyist in need a year from now, for a discount (after I've forgotten how much I paid). Just gonna float down the river of life, man!
