222-4209 - Miller Smith 220 Silverline Series High Purity Two-Stage Regulator CGA 580

Precision Analytical Control with Miller Smith Silverline

The Miller Smith 222-42-09 Silverline High Purity Analytical Two Stage Regulator is engineered for applications demanding the highest levels of precision and gas purity. Part of the renowned 220 Silverline Series, this regulator is specifically designed to manage high purity, non-corrosive pure gases and mixtures. It is an essential component for laboratory environments where stable delivery pressure is non-negotiable, regardless of fluctuations in cylinder pressure. The two-stage design steps down pressure in two increments, ensuring that the output remains constant from a full cylinder down to a nearly empty one, eliminating the need for constant manual adjustments.

Constructed with a rugged brass bar stock body, the regulator features a fully plated body, bonnet, and gauges. This chrome plating not only provides an aesthetic, professional appearance suitable for laboratory settings but also offers superior protection against environmental corrosion. A key feature of this model is the stainless steel diaphragm, which provides a non-contaminating surface for the gas stream and allows for extremely precise control of delivery pressure. The unit is also equipped with a filtered seat, which adds another layer of gas stream purity and significantly extends the service life of the seat by preventing particulate damage.

Safety and functionality are paramount in the 222-42-09. It includes a built-in capturable preset safety relief valve to protect downstream components from over-pressurization. The regulator is capable of withstanding vacuums generated during purging operations, making it versatile for various setup procedures. The large 2-1/2 inch single scale gauges are easy to read, ensuring operators can monitor cylinder and delivery pressure at a glance. This specific model comes equipped with a 1/8-inch tube stainless steel needle valve on the outlet, allowing for fine-tuning of flow rates directly at the regulator.

Ideal for use with inert gases such as Nitrogen, Argon, and Helium via its CGA 580 connection, this regulator supports a delivery range of 0-100 PSI (with a max inlet of 3500 PSI). Whether used for carrier gases or calibration mixtures, the Miller Smith 222-42-09 delivers the reliability and accuracy required for critical analytical work.
