What is the difference between a single-stage and a dual-stage regulator?Single-stage regulators lower pressure in a single step to produce pressure within a defined range. Regulators devised accordingly will show a small variation in delivery pressure as the cylinder pressure falls during use. For this reason, single-stage regulators are most appropriate for applications where a constant outlet pressure is not urgent, where an operator can supervise and readjust pressure, or where inlet pressure is stable. Dual-stage regulators perform the same function as single-stage regulators. However, delivery pressure holds constant as cylinder pressure declines. Increased accuracy in pressure control is kept because the pressure reduction is delivered in two steps. Dual-stage regulators are favored for applications calling for a constant outlet pressure throughout the life of a gas cylinder.Access our catalog for more information on gas regulators or reach us at or email@example.com.
