222-2005 - Miller Smith Silverline 220 Series High Purity 2-Stage Regulator CGA 346

Precision Control for Analytical Applications

The Miller Smith 222-20-05 Silverline High Purity Analytical Two Stage Regulator is engineered to meet the rigorous demands of laboratory and analytical environments. Part of the esteemed 220 Silverline Series, this regulator is specifically designed for applications requiring absolute gas purity and unwavering pressure stability. The core of its performance lies in the two-stage design, which steps down cylinder pressure in two distinct phases. This configuration ensures that the delivery pressure remains constant even as the cylinder pressure drops from full to nearly empty, a critical feature for long-duration processes like gas chromatography where pressure drift can compromise results.

Material selection is paramount in high-purity applications. This model features a stainless steel diaphragm that provides precise control while eliminating the risk of elastomeric off-gassing that could contaminate the gas stream. The seat is filtered to further enhance purity and protect the internal mechanism from particulate damage, significantly extending the service life of the unit. The body, bonnet, and gauges are fully plated, offering superior protection against environmental corrosion and maintaining a clean, professional appearance suitable for laboratory settings.

Safety and usability are also key components of the 222-20-05. It includes a built-in capturable preset safety relief valve that protects downstream equipment from over-pressurization. The large 2-1/2 inch single scale gauges are easy to read, allowing operators to monitor cylinder and delivery pressure at a glance. With a CGA 346 connection, this regulator is tailored for use with compressed air and compatible specialty gas mixtures, delivering a pressure range of 0-100 PSIG. Whether used for thermal conductivity, flame ionization, or electron capture systems, this Miller Smith regulator delivers the reliability professionals demand.
