220-0309 - Miller Smith Silverline 220 Series Analytical Two-Stage Regulator, CGA 580, 0-15 PSI

Precision Control for Analytical Applications

The Miller Smith 220-03-09 Silverline High Purity Analytical Two Stage Regulator is engineered to meet the rigorous demands of laboratory and analytical environments. Designed specifically for non-corrosive pure gases and mixtures, this regulator excels in applications where maintaining a constant delivery pressure is critical, regardless of fluctuations in the supply cylinder. It is particularly well-suited for controlling carrier gases and calibration mixtures used in gas chromatography techniques such as thermal conductivity, flame ionization, flame photometry, and electron capture.

Advanced Two-Stage Design

The two-stage architecture of the Series 220 Silverline ensures that output pressure remains stable from a full cylinder down to nearly empty. This eliminates the need for frequent manual adjustments and ensures the integrity of sensitive analytical processes. The unit features a stainless steel diaphragm, which provides precise pressure control and prevents off-gassing or contamination that can occur with elastomeric diaphragms, ensuring the purity of the gas stream is maintained.

Robust Construction and Safety

Constructed from rugged brass bar stock, the body, bonnet, and gauges are fully plated to offer superior protection against corrosion and wear. The regulator includes a filtered seat that not only enhances gas purity but also extends the service life of the seat mechanism by preventing particulate damage. Safety is paramount in high-pressure environments; therefore, this model includes a built-in capturable preset safety relief valve to protect components from over-pressurization. Additionally, the design is robust enough to withstand vacuums generated during purging operations, making it a versatile choice for complex gas delivery systems.

Key Specifications

This model comes equipped with a CGA 580 connection, suitable for inert gases like Nitrogen, Argon, and Helium. It features large, easy-to-read 2-1/2 inch single scale gauges and supports a maximum inlet pressure of 3500 PSIG. The delivery range is optimized for low-pressure applications, nominally 0-15 PSI, with gauges capable of reading vacuum (30" HG) up to 30 PSI.
