Which regulator is best for you in Denver?11/13/2018A gas regulator is a piece of equipment that moderates the gas pressure in a cylinder. The majority of cylinders have regulators that come with 2 gauges. Some regulators that are used on cylinders with gases that have changed to liquids, might not have a cylinder pressure gauge because the cylinder pressure varies only with temperature. The two most important variables that will govern whether a single stage or dual stage regulator should be employed are droop and supply pressure effect. Droop is the difference in delivery pressure between zero flow and the regulators maximum gas capacity. Supply Pressure is the difference in delivery pressure as supply pressure drops while the cylinder is emptying. A dual stage regulator shows more droop than pressure effects in Denver, while a single stage regulator should be used when there is minimal expectation of pressure variation or where occasional pressure adjustments are not problematic. Single stage regulators in general are best for shorter instances of specialty gas use. Many companies will utilize a dual stage regulator because it offers consistent delivery of pressure with no need for periodic readjustment. Both single and dual stage regulators are equipped with 2 gauges, cylinder or inlet pressure gauge and a delivery or outlet pressure gauge. A cylinder pressure gauge has a wider pressure range compared to a delivery pressure gauge. Again, whether a manufacturer opts to use a single or dual stage regulator will depend on the application.
