Does anyone know if the working pressure on this http://cgi.ebay.co.uk/Dual-Gauge-CO2-Re ... 3a4a90806a is adjustable or not? i need it to go above 1.7 bar to run a UP atomiser.
many thanks.
many thanks.
gollum456 said:don't know if you understood my question or not, but my current regulator has a fixed 'output' pressure (no main dial) of about 1.5 bar which is insufficient for my needs. i need to know if this reg http://cgi.ebay.co.uk/Dual-Gauge-CO2-Re ... 3a4a90806a is adjustable.
thanks for input anyway.
Yes this could easily be the needle valve. If the valve opening is fluctuating then it could back-pressure the upstream side if there is no check valve (or other form of isolation) in between the guage and the needle valve. The gauge might simply be showing you the back-pressure fluctuations. The design is really not clear so it's difficult to tell. The problem also could be farther downstream. Does this happen when you separate the regulator from the rest of the system such as tubing and reactor?gollum456 said:do you think its my needle valve thats causing the output pressure gauge to fluctuate? it moves back and forth about.1 to .2 of a bar and the bubble flow rate peaks and troughs (unsteady). though something tells me however unsteady the bubble rate the needle valve shouldn't be affecting the gauge itself?
gollum456 said:i am also thinking about buying this http://cgi.ebay.co.uk/ws/eBayISAPI.dll? ... 0547761217. when asked, the seller says output pressure is adjustable, though i'm not convinced they fully understand what im asking! they have said however that it is set at 2.2 bar. can anyone confirm this?
also if you look at the pictures there is a dial that appears to be in addition to the needle valve. does anyone have any ideas?
thanks!!
Well, just below the image the product description states the following:gollum456 said:gollum456 said:i am also thinking about buying this http://cgi.ebay.co.uk/ws/eBayISAPI.dll? ... 0547761217. when asked, the seller says output pressure is adjustable, though i'm not convinced they fully understand what im asking! they have said however that it is set at 2.2 bar. can anyone confirm this?

an answer for this would also be appreciated as i think this may be the same brand as the atomiser i bought. if so, then quality should be ok?
