Two stage or not two stage?
That is the question
Generally single stage regulators tend to be less expensive than two stage regulators. Now, single stage regulators can be well suited to certain applications, such as short term usage, but for continual usage they could prove a false economy.
In a single stage regulator, delivery pressure increases as cylinder pressure reduces, because there is less pressure exerted on the valve stem over time. Frequent adjustment is necessary to maintain a constant delivery pressure.
The two stage cleverly eliminates "regulator creep", by reducing the pressure in two stages. Like the single stage regulator as the cylinder pressure reduces with use, the first stage creeps, but the second stage maintains the pressure, because the pressure between stage one and two is so low. Pretty neat!
