212-4006 - Miller Smith 210 Series High Purity Regulator CGA 350 100 PSI

Technical Overview of the Miller Smith 212-40-06

The Miller Smith 212-40-06 is a premium component within the 210 Silverline Series, engineered specifically for the regulation of high purity, non-corrosive gases. This single-stage regulator is built to bridge the gap between standard industrial regulators and high-cost stainless steel units. It features a rugged brass bar stock construction that is fully plated, providing a clean, durable exterior that resists corrosion and wear in laboratory environments. The core of its performance lies in the stainless steel diaphragm, which ensures that the gas stream remains uncontaminated by elastomeric outgassing or atmospheric diffusion, a critical requirement for analytical instrumentation.

Technically, the unit is configured with a CGA 350 inlet connection, making it suitable for flammable gases such as Hydrogen, Methane, and Carbon Monoxide, provided they are in a high-purity, non-corrosive state. The regulator handles a maximum inlet pressure of 3500 PSIG and delivers a precise outlet pressure ranging from 0 to 100 PSIG. The internal design includes a filtered seat which not only aids in maintaining gas purity but also significantly extends the service life of the seat by preventing particulate damage. The regulator is also designed to withstand vacuums, a necessary feature for systems that undergo purging operations before use.

The 212-40-06 is equipped with large, 2-1/2 inch gauges that provide clear, single-scale readings, reducing the margin for error in pressure monitoring. The body is tapped for rear panel mounting, offering flexibility in installation for gas cabinets or bench setups. Safety is addressed via a built-in capturable preset safety relief valve, ensuring that over-pressure situations are managed securely. This unit represents a balanced engineering solution for professionals requiring reliable, high-purity gas control without the expense of a full stainless steel body.
