223-4002 - Miller Smith Silverline 220 Series Two-Stage Analytical Regulator CGA 320

Precision Control for Analytical Applications

The Miller Smith 223-40-02 Silverline High Purity Analytical Two-Stage Regulator is engineered to meet the rigorous demands of laboratory and analytical environments. Designed for use with high purity, non-corrosive pure gases and mixtures, this regulator ensures that your gas stream remains uncontaminated and stable. The core of its performance lies in the stainless steel diaphragm, which not only provides precise control over delivery pressure but also eliminates the risk of elastomeric contamination common in standard regulators.

This unit features a two-stage design, which is critical for applications requiring constant delivery pressure regardless of fluctuations in cylinder pressure. As the cylinder empties, single-stage regulators can experience a rise in delivery pressure; the Silverline 220 series eliminates this issue, providing a steady flow from a full cylinder down to nearly empty. The regulator is equipped with a CGA 320 inlet connection, making it suitable for Carbon Dioxide service in analytical setups.

Durability and purity are further enhanced by the filtered seat, which traps particulates to protect the seating surface and extend service life. The body, bonnet, and gauges are fully plated, offering superior protection against corrosion and maintaining a clean, professional appearance suitable for laboratory settings. The large 2-1/2 inch single scale gauges are easy to read, ensuring operators can monitor system status at a glance. Additionally, the regulator is designed to withstand vacuums generated during purging operations, a common requirement in high-purity gas handling.

Safety is paramount with the built-in capturable preset safety relief valve, which protects the regulator components from over-pressurization. Whether used for gas chromatography, thermal conductivity detectors, or flame ionization, the Miller Smith 223-40-02 delivers the reliability and precision required for sensitive analytical work.
