614-00030000 - Miller Smith 610 Series Silverline High Purity Regulator, CGA 326, 0-500 PSI

Technical Overview of the Miller Smith 610 Series Regulator

The Miller Smith 614-00-03-00-00 is a premium component within the 610 Silverline Series, engineered specifically for high-purity gas applications where contamination control is paramount. This single-stage regulator is constructed from brass nickel-plated bar stock, providing a robust housing that resists environmental corrosion while maintaining a high degree of cleanliness. The core of its performance lies in the stainless steel diaphragm. Unlike elastomeric diaphragms that can off-gas or absorb impurities, the stainless steel construction ensures that the gas stream remains unadulterated, making it suitable for analytical instrumentation and specialty gas delivery systems.

Technically, the regulator features a metal-to-metal seal between the body and the diaphragm. This design eliminates the need for O-rings in the primary seal area, which are potential sources of contamination and leakage over time. The unit is rated for a maximum inlet pressure of 3500 PSI and provides a precise delivery pressure range of 0-500 PSI. It utilizes a CGA 326 inlet connection, standard for Nitrous Oxide service in many industrial and medical-grade applications (verify specific gas compatibility protocols). The outlet is configured with a 1/4" FNPT port, allowing for versatile integration into panel mounts or direct line connections.

Fluid dynamics within the regulator are managed by a filtered seat mechanism and a 316 stainless steel filter installed at the inlet. This multi-stage filtration approach protects the delicate seating surfaces from particulate damage, significantly extending the service life of the component. Safety features include a threaded bonnet with a 1/16" FNPT capturable vent, allowing hazardous gases to be piped away safely in the unlikely event of a diaphragm failure. The regulator is also tapped for rear panel mounting, offering flexibility for installation in gas cabinets or laboratory benches.
