223-0302 - Miller Smith Silverline 220 Series High Purity Two-Stage Regulator CGA 320

Precision Control for Analytical Applications

The Miller Smith 223-03-02 Silverline High Purity Analytical Two Stage Regulator is engineered for the most demanding gas delivery applications. Designed specifically for high purity, non-corrosive pure gases and mixtures, this regulator ensures that your critical processes receive a consistent and uncontaminated flow. It is an essential tool for laboratories and industrial settings utilizing gas chromatography, including thermal conductivity, flame ionization, flame photometry, and electron capture detection methods.

Advanced Two-Stage Design

Featuring a robust two-stage design, the 223-03-02 provides precise pressure control from a full cylinder down to nearly empty. This capability is vital for applications requiring constant delivery pressures regardless of fluctuations in cylinder pressure. The regulator effectively mitigates the "decay" effect often seen in single-stage regulators, ensuring stability throughout the lifespan of the gas cylinder. With a delivery range of 0-150 PSI and a maximum inlet pressure of 3500 PSI, it offers versatility for various analytical setups.

Superior Construction and Purity

Constructed from rugged brass bar stock, the body, bonnet, and gauges are fully plated to offer superior protection against environmental factors and to maintain a clean aesthetic suitable for laboratory environments. The heart of the regulator features a stainless steel diaphragm, which provides exceptional sensitivity and precise control over outlet pressure. A filtered seat is integrated into the design to enhance gas stream purity and extend the service life of the seat assembly by preventing particulate damage. Additionally, the unit is designed to withstand vacuums generated during purging operations, maintaining integrity during cylinder changeovers.

Safety and Usability

Safety is paramount in high-pressure gas handling. The Miller Smith 223-03-02 includes a built-in capturable preset safety relief valve that automatically reseats, protecting regulator 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. This regulator connects via a CGA 320 fitting, commonly used for specific high-purity gas mixtures.
