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

Single-stage regulators reduce pressure in a single step to effect pressure within a specific range. Regulators designed in this way will show a slight variation in delivery pressure as the cylinder pressure falls during use. This is why single-stage regulators are most appropriate for jobs where a constant outlet pressure is not crucial, where an operator can supervise and readjust pressure, or where inlet pressure is steady.

Dual-stage regulators perform the same function as single-stage regulators. That said, delivery pressure holds constant as cylinder pressure decreases. Greater accuracy in pressure control is kept because the pressure reduction is achieved in two steps. Dual-stage regulators are favored for applications necessitating a constant outlet pressure for the life of a gas cylinder.
