SINGLE VS. MULTI-STAGE REGULATORS

 

A single-stage regulator reduces the cylinder pressure to delivery or outlet pressure in one step while a multi-stage regulator performs this process in two. The performance of each is influenced by mechanical characteristics and the choice of regulator thus depends on the requirements of the application.

Additionally, the two most important variables to be considered are droop and supply pressure effect.

Droop is the difference in delivery pressure between zero flow conditions and the regulator’s maximum flow capacity or the change in delivery pressure as flow is initiated and increased through the regulator.

Supply pressure effect is the variation in delivery pressure as supply pressure decreases while the cylinder empties. In most regulators, a decrease in inlet pressure causes the delivery pressure to increase.

The single-stage regulator shows little droop with varying flow rates, but a relatively large supply pressure effect. This means that the regulator will have to be continuously adjusted as the cylinder empties to maintain the desired working pressure. Generally a single-stage regulator is good for short duration applications.

Furthermore, the multi-stage regulator  shows a considerable droop , but only small supply pressure effects. However, a multi-stage regulator provides constant delivery pressure without the need for periodic adjustment. The multi-stage regulator is better suited for long duration applications.
