Which regulator is best for you in Northern Illinois?11/13/2018A gas regulator is a type of equipment that controls the gas pressure in a cylinder. The majority of cylinders have regulators with 2 gauges. Some regulators that are used on cylinders with gases that have turned 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 decreases while the cylinder releases gas. A dual stage regulator shows more droop than pressure effects in Northern Illinois, while a single stage regulator should be employed when there is little anticipation of pressure variation or where occasional pressure adjustments are not problematic. Single stage regulators in general are best for shorter periods of gas usage. Many companies will utilize a dual stage regulator because it provides a constant 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 higher 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.
