322-70310000 - Miller Smith 320 Silverline Series High Purity Stainless Steel Two-Stage Regulator, CGA 705, 0-100 PSI

Precision Control for High Purity Applications

The Miller Smith 322-70-31-00-00 High Purity Corrosion Resistant Stainless Steel Two Stage Regulator is engineered for the most demanding gas delivery applications. Part of the esteemed 320 Silverline Series, this regulator is designed to handle both corrosive and non-corrosive gases with unmatched precision. For laboratory environments, analytical instrumentation, and petrochemical processes where gas purity is paramount, the 322 series delivers reliability you can trust.

Superior Materials for Corrosive Environments

Constructed from high-grade 316 Stainless Steel bar stock, the body of this regulator offers exceptional resistance to corrosion, ensuring a long service life even when used with aggressive media. The wetted parts, including the 316 stainless steel filtered seat and PCTFE components, are specifically selected to maintain the integrity of the gas stream. This focus on material quality prevents contamination and ensures that the high purity of your specialty gases is preserved from the cylinder to the point of use.

Stable Two-Stage Performance

One of the standout features of the Miller Smith 322 series is its two-stage design. Unlike single-stage regulators that may experience a rise in delivery pressure as the cylinder pressure drops (the decaying inlet characteristic), this two-stage regulator provides a constant, stable delivery pressure throughout the life of the cylinder. This stability is critical for sensitive experiments and processes where pressure fluctuations could compromise results. The convoluted stainless steel diaphragm further enhances this precision, offering sensitive response to pressure changes.

Safety and Integrity

Safety is built into every aspect of this regulator. It features a unique metal-to-metal diaphragm seal which provides maximum leak integrity, a crucial requirement when handling hazardous or toxic gases. Additionally, the bonnet includes a captured vent port (1/16” FNPT), allowing users to pipe vented gases away to a safe location in the rare event of a diaphragm failure. With large, easy-to-read 2-1/2 inch gauges and a design that withstands internal vacuums during purging, the Miller Smith 322-70-31-00-00 is the professional choice for high-purity gas regulation.
