212-0008 - Miller Smith 210 Silverline High Purity Single Stage Regulator, CGA 540, 0-100 PSI

Technical Analysis: Miller Smith 212-00-08 Silverline Regulator

The Miller Smith 212-00-08 is a premium component within the 210 Silverline Series, engineered specifically for high purity analytical applications. This single-stage regulator is designed to manage non-corrosive gases, specifically utilizing a CGA 540 inlet connection typically associated with Oxygen service in industrial and laboratory settings. The unit features a delivery pressure range of 0-100 PSIG, making it suitable for applications requiring stable, moderate pressure control without the need for the ultra-stable delivery curve of a two-stage system.

A critical technical feature of this regulator is its stainless steel diaphragm. Unlike elastomeric diaphragms, the stainless steel construction prevents inboard diffusion of atmospheric contaminants and ensures that the gas stream remains pure, preserving the integrity of sensitive analytical instruments. The body and bonnet are machined from rugged brass bar stock and are fully plated to resist corrosion and maintain a clean aesthetic suitable for laboratory environments. The seat assembly includes a filter to trap particulates, further protecting the seat from damage and extending the operational lifespan of the regulator.

The 212-00-08 is equipped with large, 2-1/2 inch single-scale gauges that provide clear readings of both cylinder and delivery pressure. The outlet is a 1/4" FNPT connection, allowing for versatile integration with various tube fittings or piping systems. Safety is addressed via a built-in capturable preset safety relief valve. This regulator is rated for a maximum inlet pressure of 3500 PSIG and is capable of withstanding vacuums generated during purging operations, a common requirement in high-purity gas handling procedures.

This unit is specifically recommended for instrument analysis, automotive emissions testing, biological laboratories, and chemical process plants where brass construction is chemically compatible with the process environment. The rear-panel mounting capability adds flexibility for installation in gas cabinets or benchtop manifolds.
