223-0009 - Miller Smith Silverline 220 Series Two-Stage Analytical Regulator CGA 580

Precision Control for Analytical Applications

The Miller Smith 223-00-09 Silverline High Purity Analytical Two-Stage Regulator is engineered for professionals who demand exacting standards in gas delivery. Designed specifically for high purity, non-corrosive pure gases and mixtures, this regulator is a staple in laboratory environments, gas chromatography setups, and emission monitoring systems. The core of its performance lies in its two-stage design, which reduces cylinder pressure in two steps. This mechanism ensures that the delivery pressure remains constant even as the cylinder pressure drops from full to empty, eliminating the need for frequent manual adjustments during critical procedures.

Superior Materials for Purity

Contamination is the enemy of analytical accuracy. That is why the 220 Silverline series features a stainless steel diaphragm. Unlike rubber or neoprene diaphragms that can off-gas or absorb impurities, stainless steel provides a non-reactive barrier that preserves the integrity of your gas stream. Coupled with a filtered seat, this regulator prevents particulate contamination, extending the service life of the unit and protecting downstream instrumentation. The body, bonnet, and gauges are fully plated, offering superior corrosion resistance and a clean, professional aesthetic suitable for lab environments.

Rugged and Reliable Construction

While designed for delicate analytical work, the 223-00-09 is built with industrial durability. Constructed from rugged brass bar stock, it can withstand the rigors of daily use. It features large, 2-1/2 inch single-scale gauges that are easy to read at a glance, ensuring operators can monitor system status effectively. The unit also includes a built-in capturable preset safety relief valve, adding an essential layer of safety by protecting components from over-pressurization. With a maximum inlet pressure of 3500 PSI and a delivery range up to 150 PSI via a CGA 580 connection, this regulator is the ideal choice for managing inert gases like Argon, Nitrogen, and Helium in high-stakes applications.
