Which regulator is best for you in Southern California?

A gas regulator is a piece of equipment that moderates 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 changed to liquids, might not have a cylinder pressure gauge because the cylinder pressure changes only with temperature. The two most critical factors that will determine 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 Southern California, while a single stage regulator should be used when there is little anticipation of pressure variation or when adjusting the pressure on specialty gas is infrequent and not problematic. Single stage regulators in general are best for shorter duration gas usage. Most manufacturers will utilize a dual stage regulator because it provides a constant delivery of pressure without warranting the occasional change in pressure.

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 than a delivery pressure gauge.

Again, whether a manufacturer opts to use a single or dual stage regulator will depend on the application. To find out more on which regulator is most useful for you in Southern California, please contact WestAir Specialty Gases and Equipment.
