Type of Regulator (check one)

Single-Stage Single-stage regulators reduce the pressure of the gas source to the desired delivery pressure in one step. They do not provide the precise control of delivery pressure that can be achieved with a dual-stage pressure regulator, but they are more economical. Single-stage pressure regulators should be used for applications where you can monitor and regulate the pressure downstream.

Dual-Stage Dual-stage regulators provide more precise pressure control by reducing the gas source pressure to the desired delivery pressure in two steps. They are recommended for supplying gas where constant delivery pressure is critical, especially if your gas source is a high-pressure cylinder. As the cylinder gas is used, the inlet pressure to the regulator from the cylinder decreases. A dual-stage regulator compensates for the decrease and maintains a constant delivery pressure; whereas, a single-stage regulator does not.

In-Line Line regulators are single-stage pressure regulators that are used to provide point-of-use pressure monitoring and control. These pressure regulators are installed directly into gas lines, immediately before your instrumentation, to ensure the appropriate gas pressure is being delivered to your instrument. A dual-stage or single-stage pressure regulator should always be installed upstream of the in-line regulator to ensure adequate pressure control.
