223-4006 - Miller Smith Silverline 220 Series High Purity Two-Stage Regulator CGA 350

Precision Control for Analytical Applications

The Miller Smith 223-40-06 Silverline High Purity Analytical Two-Stage Regulator is engineered for applications demanding the highest levels of gas stream purity and pressure stability. Designed specifically for non-corrosive pure gases and mixtures, this regulator is an essential component for sensitive analytical instruments, including gas chromatographs utilizing thermal conductivity, flame ionization, flame photometry, and electron capture detectors. Its robust construction and precise engineering ensure reliable performance in laboratory and industrial testing environments.

Advanced Two-Stage Design

Unlike single-stage regulators that experience delivery pressure decay as the cylinder empties, the 223-40-06 utilizes a two-stage mechanism. This design steps down the pressure in two increments, providing a constant delivery pressure regardless of fluctuations in the inlet cylinder pressure. This feature is critical for analytical procedures where pressure stability directly impacts the accuracy of results. The regulator allows for precise control from full to nearly empty cylinders, maximizing gas usage without compromising performance.

Superior Materials and Construction

To maintain gas purity, the regulator features a stainless steel diaphragm that prevents contamination and diffusion often associated with elastomeric diaphragms. The seat is filtered to protect the internal mechanism from particulates, extending service life and ensuring a clean gas stream. The body, bonnet, and gauges are fully plated, offering superior protection against environmental factors and maintaining a clean, professional appearance suitable for laboratory settings. Additionally, the unit is capable of withstanding vacuums generated during purging operations, making it versatile for complex gas management systems.

Safety and Usability

Safety is paramount in high-pressure gas handling. This regulator includes a built-in capturable preset safety relief valve that protects components 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 maximum inlet pressure of 3500 PSI and a delivery range optimized for 0-150 PSI applications, the Miller Smith 223-40-06 is the definitive choice for professionals requiring exacting standards in gas regulation.
