7 The High-Pressure Source
So far, the projects we’ve been building have relied on a low-pressure regulator. This typically means that we’ve been receiving propane at about ½ psi. While lots of interesting things are possible with propane at that pressure, even more interesting things are possible with lots more.
High-pressure regulators are available in a variety of ranges. Most of the ones sold to consumers are adjustable and provide a range of outputs beginning at 0 psi (closed) and going as high as 100 psi (700 kPa). Regulators with higher output pressures are available, but for our purposes, I’m going to recommend a 0–60 psi regulator ...
