320-00310000 - Miller Smith 320 Series High Purity Stainless Steel Two-Stage Regulator, 25 PSI, CGA 705

Precision Control for Specialty Gases

The Miller Smith 320 Series High Purity Two-Stage Regulator is engineered for the most demanding applications involving corrosive and non-corrosive gases. Designed with a focus on purity and stability, this regulator features a 316 stainless steel bar stock body and wetted parts, ensuring compatibility with a wide range of specialty gases. The Model 320-00-31-00-00 is specifically configured with a CGA 705 connection and delivers a precise pressure range of 0-25 PSI, making it ideal for sensitive laboratory and industrial processes.

Uncompromising Purity and Safety

Contamination is the enemy of high-purity applications. That is why the 320 Series utilizes a 316 stainless steel filtered seat to maintain gas stream purity and extend the service life of the unit. The unique metal-to-metal diaphragm seal provides maximum leak integrity, eliminating the risk of off-gassing associated with elastomeric seals. For added safety when handling hazardous gases, the regulator includes captured vent ports in the bonnet (1/16" FNPT), allowing for the safe venting of gases in the unlikely event of a diaphragm failure.

Stable Delivery Pressure

As a two-stage regulator, the 320 Series offers a significant advantage over single-stage models by providing constant delivery pressure regardless of fluctuations in inlet pressure. As your gas cylinder empties and pressure drops, this regulator compensates automatically, ensuring your process receives a steady flow without the need for constant manual adjustment. This feature is critical for analytical instruments and precise chemical reactions where stability is paramount.

Rugged and Versatile Design

Built to withstand the rigors of industrial use, the regulator features large, easy-to-read 2-1/2 inch single scale gauges and a convoluted stainless steel diaphragm for precise pressure control. It is also designed to withstand internal vacuums during purging operations, a necessary step when changing cylinders in high-purity systems. Whether for research, petrochemical, or pharmaceutical applications, the Miller Smith 320 Series delivers the reliability and performance professionals trust.
