Regulators again

[tubamanandy]

Other than CO2 Art in the UK, can anyone recommend a decent twin-stage CO2 regulator that also has a good needle valve ?

I'm still using a CO2 Art model (and had one before this one) and I'm not impressed. Despite supposedly having a better quality needle valve it does nothing - I'm continually (daily) having to mess about with the small knurled adjustment.

I think they are a great company but I dont seem to have any luck with their regulators despite paying around £60-70 for it.

You shouldn't have to be adjusting it every day, suggests you have a leak somewhere. I'm a big fan of the Co2 Art regs, and when i've had a problem with them, they've talked me through the steps to repair them.

I would suggest a leak if your rate varies from day to day.

It is proper CO2 tubing you are using ?

Also can be due to excessive lengths of CO2 tubing. When I first setup my CO2 I cut the 3 meter odd of CO2 tubing to connect the various bits, but left the rest connecting one way valve to diffuser, possibly 2 meters. I found it very hard to set reliable CO2 rate, the rate varying between b*gger all and monsterous flood each time CO2 came on. Cutting the tube to more appropriate lengths, I now find the CO2 rate is infinitely adjustable (using my CO2 supermarket single stage regulator) from b*gger all to monsterous and comes on at exactly the same rate every day.

No leaks I can find but fairly long pipe length (proper CO2 pipe) - I feed my CO2 into an external reactor, dont suppose I need a large output pressure as I'm not putting the CO2 through any form of diffuser.

Any ideas what output pressure I should be using ? Currently set at around 20psi and I know diffusers need a bit more (30psi ??)

When I do get the bubble rate spot on, next day its either way too much or too little - just no consisitency

Do you have the needle valve that you can lock off with the little nut? Maybe that's not nipping up tight enough?
