Re: CO2 Regulation Pressure

No, no, no... I posted my message wrong.  I was recalling about how another APD reader had found a lower pressure regulator at lowe's... something around 200 psi max (probably for
an air compressor).  My query was if anyone had thought of using this regulator AFTER a high pressure regulator INSTEAD of a needle vavle.  A needle vavle is designed for flow
control rather than pressure control.  Could this be a feasible, if not better (easier to control) alternative.  I was not at all thinking about using just the single low pressure
regulator on a tank where the psi is up around 1000.

$150, this little gem looks promising.  It's a small compressed air
regulator sold at Lowe's for $20.  It would need a couple of  fittings
and maybe a needle valve to adapt to a CO2 cylinder, but total cost
should be $30.  It is rated to about 200lbs.  Anyone know the partial
pressure of CO2 off the top of their heads?"
Be very careful here.  My CO2 tanks run at about 900 psi or so.  I would
be scared to death to use equipment rated for 200 psi.  Don't do this
unless someone who knows what they're doing explains why it would be
