611-03020000 - Miller Smith Silverline 610 Series High Purity CO2 Regulator, 0-50 PSI

Precision Control for High Purity Applications

The Miller Smith 611-03-02-00-00 Silverline High Purity Brass Single Stage Regulator is an exemplary piece of engineering designed to meet the rigorous demands of specialty gas delivery. Part of the esteemed 610 Series Silverline, this regulator is specifically crafted to prevent contamination in high-purity systems, making it an ideal choice for laboratory, analytical, and process control applications where gas integrity is paramount. The unit features a CGA 320 connection, standard for Carbon Dioxide (CO2) service, and provides a delivery pressure range suitable for sensitive downstream equipment.

Advanced Construction and Materials

At the core of this regulator's performance is its superior construction. The body is machined from brass nickel-plated bar stock, offering a robust housing that resists environmental corrosion while maintaining a clean aesthetic suitable for lab environments. Unlike standard industrial regulators that may use rubber or neoprene diaphragms, the 611-03-02-00-00 utilizes a specially designed stainless steel diaphragm. This choice of material is critical; it eliminates the risk of off-gassing and absorption associated with elastomers, ensuring that the gas stream remains as pure as the source. The metal-to-metal seal between the body and the diaphragm further reinforces this containment, providing a leak-tight seal that withstands the test of time.

Operational Reliability and Safety

Reliability is engineered into every aspect of the Silverline series. The regulator features a filtered seat mechanism that adds an extra layer of protection for gas stream purity. Additionally, a 316 stainless steel filter is integrated to capture any particulate matter before it enters the regulation stage, protecting the seat and ensuring consistent performance. For safety and versatility, the bonnet is equipped with a 1/16-inch FNPT port, allowing for the capture and venting of gases in the unlikely event of a diaphragm failure—a crucial feature when managing gases in enclosed or sensitive environments. The regulator is also capable of withstanding an internal vacuum, making it versatile for various purging and evacuation procedures.

Installation and Versatility

Designed with the end-user in mind, the Miller Smith 611-03-02-00-00 offers flexible installation options. The threaded bonnet and tapped body facilitate easy panel mounting, allowing for clean integration into gas management panels or instrument benches. The 2-1/2 inch single scale gauge provides clear, easy-to-read pressure monitoring, ensuring operators can verify system status at a glance. Whether used for chromatography, research, or high-precision manufacturing, this regulator delivers the stability and purity required for critical operations.
