220-0007 - Miller Smith Silverline 220 Series High Purity Two-Stage Regulator, CGA 510, 0-15 PSI

Precision Control for Analytical Applications

The Miller Smith 220-00-07 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, such as in gas chromatography (thermal conductivity, flame ionization, flame photometry, and electron capture). The two-stage design is fundamental to its performance, allowing for precise control from a full cylinder down to nearly empty, effectively negating the 'decay' effect often seen in single-stage counterparts.

Superior Materials and Construction

At the heart of the 220 Series is a stainless steel diaphragm. Unlike elastomeric diaphragms that can outgas or absorb contaminants, stainless steel ensures the integrity of the gas stream is preserved, making it ideal for high-purity applications. The regulator body and bonnet are constructed from rugged brass bar stock and are fully plated to provide superior protection against corrosion and environmental wear. A filtered seat mechanism further enhances gas stream purity while extending the service life of the internal components by preventing particulate damage.

Operational Safety and Versatility

Safety and ease of use are paramount in the Silverline design. The unit features a built-in capturable preset safety relief valve that protects downstream 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. Furthermore, the regulator is designed to withstand vacuums generated during purging operations, a common requirement in high-purity gas handling. With a delivery range of 0-15 PSIG and a CGA 510 inlet, this model is perfectly suited for low-pressure, high-precision tasks.
