What is the difference between a single-stage and a dual-stage regulator?Single-stage regulators lower pressure in just one step to effect pressure within a specified range. Regulators designed in this way will show a small variation in delivery pressure as the cylinder pressure decreases during use. This is why single-stage regulators are the right choice for uses where a constant outlet pressure is not urgent, where an operator can supervise and readjust pressure, or where inlet pressure is steady. Dual-stage regulators provide the same function as single-stage regulators. But delivery pressure holds steady as cylinder pressure falls off. Higher accuracy in pressure control is sustained because the pressure reduction is achieved in two steps. Dual-stage regulators are suggested 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 818-647-7427 or firstname.lastname@example.org.
