222-4009 - Miller Smith Silverline 2-Stage High Purity Regulator CGA 580 0-100 PSI

Industrial Grade High Purity Regulation

The Miller Smith 222-40-09 from the Silverline 220 Series is a premium two-stage regulator designed to meet the rigorous demands of high-purity gas applications. Unlike single-stage regulators that may experience pressure rise as the cylinder empties, this two-stage unit maintains a steady output pressure throughout the life of the cylinder. This reliability makes it the ideal choice for controlling carrier gases or calibration mixtures used in sensitive equipment like thermal conductivity detectors, flame ionization detectors, and flame photometry systems.

Robust Construction for Long Life

Durability meets precision in the 222-40-09. The regulator features a heavy-duty brass bar stock construction that is plated for a clean, professional finish and enhanced resistance to oxidation. The stainless steel diaphragm is a key feature, offering superior sensitivity and longevity compared to elastomeric alternatives, while ensuring that the gas stream remains uncontaminated. The seat assembly includes a filter to block debris, protecting the seat from damage and ensuring a leak-tight seal over time. This attention to detail ensures that the regulator performs consistently even in demanding environments.

Specifications and Compatibility

This model comes equipped with a CGA 580 inlet connection, suitable for standard inert gas cylinders such as Nitrogen, Argon, and Helium. It offers a delivery pressure range of 0-100 PSIG, easily adjustable via the ergonomic knob. The outlet is configured with a 1/4" FNPT connection, often paired with a needle valve for fine flow control. Rated for a maximum inlet pressure of 3500 PSIG, the Miller Smith 222-40-09 is a robust solution for welders, lab technicians, and industrial operators requiring high-purity gas regulation without compromise.
