222-4006 - Miller Smith Silverline 220 Series High Purity Two-Stage Regulator CGA 350

Precision Control for Analytical Applications

The Miller Smith 222-40-06 Silverline High Purity Analytical Two Stage Regulator is engineered for the most demanding laboratory and industrial applications where gas purity and pressure stability are paramount. As part of the renowned Silverline 220 Series, this regulator is specifically designed to handle high purity, non-corrosive gases and mixtures, making it an essential tool for gas chromatography, flame ionization, and other sensitive analytical processes. The unit features a CGA 350 connection, typically used for flammable gases such as Hydrogen and Methane, ensuring a secure and standard fit for your specialty gas cylinders.

Two-Stage Design for Constant Pressure

One of the standout features of the 222-40-06 is its two-stage construction. Unlike single-stage regulators that allow delivery pressure to rise as the cylinder pressure decays, this two-stage mechanism maintains a constant delivery pressure from a full cylinder down to nearly empty. This characteristic is critical in analytical settings where even minor fluctuations in carrier gas pressure can skew results or disrupt calibration. With a delivery range of 0-100 PSIG, users can fine-tune the output with exceptional accuracy.

Superior Materials and Construction

To maintain the integrity of high-purity gas streams, Miller Smith has equipped this regulator with a stainless steel diaphragm. This material choice prevents the off-gassing associated with rubber diaphragms and provides a non-reactive surface for the gas stream. The body, bonnet, and gauges are plated to offer superior protection against environmental corrosion and to maintain a clean, professional appearance suitable for laboratory environments. Additionally, a filtered seat is integrated into the design to trap particulates, further ensuring gas stream purity and extending the service life of the regulator components.

Safety and Reliability

Safety is built into the core of the Silverline series. The regulator includes a built-in capturable preset safety relief valve that protects downstream equipment and the regulator itself from over-pressurization. The rugged brass bar stock construction ensures durability, while the large 2-1/2 inch gauges provide clear, easy-to-read pressure monitoring. Whether you are purging systems or running continuous analytical tests, the Miller Smith 222-40-06 delivers the reliability and precision required for high-stakes environments.
