--OK here's the thing: I'm trying to push a good flow of
propane into a flaming widget but I'm only wanting to do it at
about 10psi. There's a wee pressure regulator attached to the
widget (threaded 1/4" pipe but I could go up to 3/8") but it's
definitely acting as a flow restrictor, not just a pressure
regulator. Is there a device that can solve the problem?


The average individual appliance regulator has a needle valve oriface
that's very small. You won't get any appreciable flow through it.

Most gas regulators won't tune up to 10psi, either. I don't
remember, but think it was in the low tens of inches of water column.

Our professional flame effects use gas _rated_ high-flow regulators
with 1/2" piping. I'd think a very large welding gas regulator
might suit the purpose.

A cheaper and more readily available regulator would be one for a high
BTU/Hr "jet" burner outdoor cooker. I have one that is rated at
105,000 BTU/Hr which has an adjustable regulator that goes from 0-10
PSI. The whole unit was $60 at a local sporting goods store.

Fisher (I think) makes propane regs that are adjustable up to either 30 or
60 psi . I have the 60 psi version on my foundry burner , but have yet to go
over 30 . I think I'm pumping around 80,000 BTU's thru it when it's at 30
psi (.030" orifice/1" Mikey burner), all I know is it'll take 10 lbs of
aluminum from ambient (cold furnace) to molten in under 20 minutes .
