What is the difference between a single-stage and a dual-stage regulator?

Single-stage regulators lower pressure in one step to produce pressure within a specific range. Regulators designed accordingly will show a slight variation in delivery pressure as the cylinder pressure decreases during use. For this reason, single-stage regulators are the right choice for jobs where a constant outlet pressure is not crucial, where an operator can monitor and readjust pressure, or where inlet pressure is constant.

Dual-stage regulators serve the same function as single-stage regulators. But delivery pressure stays steady as cylinder pressure declines. Greater accuracy in pressure control is sustained because the pressure reduction is performed in two steps. Dual-stage regulators are favored for applications calling for a constant outlet pressure over the life of a gas cylinder.
