Miller Smith 320 Series High Purity Stainless Steel Regulator, CGA 320, 50 PSI

Miller Smith 320 Series: The Gold Standard in Stainless Regulators

For professionals requiring the ultimate in gas control and durability, the Miller Smith 321-00-20-00-00 High Purity Two-Stage Regulator delivers unmatched performance. This regulator is part of the elite Silverline 320 Series, specifically engineered for specialty gas delivery where standard brass regulators would fail or contaminate the process. Equipped with a Stainless Steel CGA 320 fitting, this unit is tailored for Carbon Dioxide (CO2) applications requiring a delivery pressure up to 50 PSI. Its robust design supports a maximum inlet pressure of 3500 PSI, ensuring compatibility with high-pressure cylinders.

The core of this regulator's performance lies in its materials and engineering. The body is machined from 316 stainless steel, providing a non-reactive path for gases. This is complemented by a PCTFE seat, chosen for its chemical resistance and durability. The unique metal-to-metal diaphragm seal eliminates the need for elastomeric seals that can degrade or off-gas over time, ensuring that the gas leaving the regulator is as pure as the gas entering it. This feature is particularly vital for chromatography, laser mixtures, and emission monitoring systems.

Operational precision is guaranteed by the two-stage reduction mechanism. By stepping down the pressure in two stages, the regulator isolates the delivery pressure from fluctuations in the supply cylinder. This means you can set your required 50 PSI output and trust it to remain stable until the tank is empty, without the need for constant manual adjustment. The large, 2-1/2 inch single-scale gauges provide clear, at-a-glance readings of both inlet and delivery pressures, improving operator efficiency and safety.

Designed with versatility in mind, the regulator features front and rear bonnet threading for panel mounting, allowing for seamless integration into gas management systems or laboratory benches. Note that for hazardous gas applications, a Cross Purge Assembly is recommended to ensure effective purging during cylinder changes. Whether for industrial research or high-tech manufacturing, the Miller Smith 321-00-20-00-00 offers the reliability and precision that industry leaders trust.
