320-00210000 - Miller Smith 320 Silverline SS Two-Stage Regulator CGA 326 25 PSI

Precision Control for High Purity Applications

The Miller Smith 320-00-21-00-00 is a premium high purity, corrosion-resistant two-stage regulator designed for the most demanding laboratory and industrial applications. Part of the renowned 320 Silverline Series, this regulator is engineered to deliver precise and stable pressure control for both corrosive and non-corrosive gases. The unit is constructed from high-grade 316 stainless steel bar stock, ensuring superior resistance to corrosion and maintaining the integrity of high-purity gas streams.

Advanced Two-Stage Design

Unlike single-stage regulators that experience a rise in delivery pressure as the cylinder pressure drops, the Miller Smith 320 Series utilizes a two-stage mechanism. This design provides a constant delivery pressure throughout the life of the cylinder, making it ideal for analytical instruments and critical processes where pressure stability is paramount. The regulator features a convoluted stainless steel diaphragm that offers exceptional sensitivity and control, coupled with a metal-to-metal diaphragm seal that ensures maximum leak integrity.

Safety and Durability

Safety is a core component of the 320 Series design. It includes captured vent ports (1/16" FNPT) in the bonnet, allowing users to safely pipe hazardous or toxic gases away from the work area in the unlikely event of a diaphragm failure. The regulator is also designed to withstand internal vacuums, making it suitable for purging operations essential in high-purity environments. A 316 stainless steel filtered seat further protects the gas stream from particulate contamination and extends the service life of the regulator.

Key Specifications

This specific model comes equipped with a CGA 326 inlet connection, typically used for specific corrosive or specialty gases (such as Nitrous Oxide in certain purity grades), and offers a delivery pressure range of 0-25 PSIG. The large 2-1/2 inch gauges provide clear, easy-to-read pressure monitoring. Whether for chromatography, research, or semiconductor manufacturing, the Miller Smith 320 Series delivers the reliability and performance professionals trust.
