222-2002 - Miller Smith Silverline 220 Series High Purity Two-Stage Regulator CGA 320

Precision Control for Analytical Applications

The Miller Smith 222-20-02 Silverline High Purity Analytical Two Stage Regulator is engineered to meet the rigorous demands of laboratory and analytical environments. Designed specifically for high-purity, non-corrosive gas applications, this regulator is an essential component for professionals utilizing gas chromatography, flame ionization, thermal conductivity, and electron capture systems. Its primary function is to deliver a stable, consistent flow of carrier gases or calibration mixtures, ensuring the integrity of your analytical results.

Advanced Two-Stage Design

In analytical settings, pressure stability is paramount. The 222-20-02 utilizes a sophisticated two-stage design which reduces cylinder pressure in two steps. This configuration allows the regulator to maintain a constant delivery pressure from a full cylinder down to a nearly empty one. Unlike single-stage regulators that may exhibit a "decaying" outlet pressure as the inlet pressure drops, this Silverline series regulator provides the unwavering stability required for sensitive instrumentation.

Material Integrity and Purity

Contamination is the enemy of high-purity gas delivery. To combat this, Miller Smith has equipped this regulator with a stainless steel diaphragm. Unlike elastomeric diaphragms that can outgas or absorb contaminants, stainless steel provides a non-reactive barrier that preserves the purity of the gas stream. Furthermore, the regulator features a filtered seat that prevents particulate matter from entering the gas stream, extending the service life of the seat and ensuring the gas remains pure for downstream equipment. The body, bonnet, and gauges are fully plated, offering superior protection against environmental corrosion and maintaining a clean, professional appearance suitable for laboratory settings.

Operational Safety and Versatility

Safety is integrated into the core of the 222-20-02. It includes a built-in capturable preset safety relief valve that protects regulator components and downstream equipment from over-pressurization. Additionally, the regulator is designed to withstand vacuums generated during purging operations, a critical feature for maintaining system purity during cylinder changeouts. With a CGA 320 connection, this unit is tailored for Carbon Dioxide service, supporting delivery pressures up to 100 PSIG with a maximum inlet of 3500 PSIG.
