223-0000 - Miller Smith 220 Series Silverline High Purity Two-Stage Regulator, 1/4 FNPT

Precision Control for Analytical Applications

The Miller Smith 223-00-00 Silverline High Purity Analytical Two-Stage Regulator is engineered for the rigorous demands of laboratory and analytical environments. Designed specifically for high purity, non-corrosive pure gases and mixtures, this regulator ensures that your critical processes receive a stable and contaminant-free gas supply. The core of its performance lies in its two-stage design, which provides constant delivery pressure regardless of fluctuations in the inlet cylinder pressure—a crucial feature for long-duration tests and chromatography applications where stability is paramount.

Constructed with a rugged brass bar stock body, the regulator is fully plated (body, bonnet, and gauges) to offer superior protection against environmental factors and to maintain a clean aesthetic suitable for lab settings. The unit features a stainless steel diaphragm that not only enhances the precision of pressure control but also preserves the purity of the gas stream by preventing off-gassing or contamination often associated with elastomeric diaphragms. A filtered seat further extends service life and ensures gas stream purity.

This model is equipped with 1/4" FNPT inlet and outlet connections, allowing for versatile integration into panel mounts or custom piping systems. It is capable of withstanding vacuums generated during purging operations, making it highly adaptable for complex gas delivery setups. Safety is addressed with a built-in capturable preset safety relief valve that protects components from over-pressurization.
