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 crafted in this manner will show a slight variation in delivery pressure as the cylinder pressure falls during use. Because of this, single-stage regulators are most appropriate for uses where a constant outlet pressure is not urgent, where an operator can watch and readjust pressure, or where inlet pressure is steady. Dual-stage regulators fulfill the same function as single-stage regulators. That said, delivery pressure stays the same as cylinder pressure declines. Higher accuracy in pressure control is maintained because the pressure reduction is brought about in two steps. Dual-stage regulators are favored for applications calling for a constant outlet pressure over the life of a gas cylinder.Access our catalog for more information on gas regulators or reach us at 855-998-4875 or email@example.com.
