254-0008 - Miller Smith 250 Series Silverline High Purity Regulator, CGA 540, 0-200 PSI

Precision Analytical Control for Liquid Cylinders

The Miller Smith 254-00-08 Silverline High Purity Analytical Liquid Cylinder Regulator is engineered to meet the rigorous demands of laboratory and analytical environments. Designed specifically for use with liquid cylinders, this regulator features a CGA 540 inlet connection, making it the standard choice for high-purity oxygen applications. The 250 Silverline series is distinguished by its commitment to maintaining gas purity from the cylinder to the point of use. A key component of this system is the exclusive Sure-Seat™ filtered seat technology. This innovation prevents microscopic contamination from entering the seating area, a common cause of regulator failure and drift, thereby significantly reducing maintenance costs and operational downtime.

Constructed for resilience and precision, the regulator boasts a nickel-plated body, bonnet, and gauges. This plating is not merely aesthetic; it provides a robust shield against corrosion, extending the service life of the unit even in challenging environments. At the heart of the regulator lies a large 1-7/8 inch stainless steel diaphragm. Unlike elastomeric diaphragms, stainless steel offers superior sensitivity and does not off-gas, ensuring that the purity of the gas stream is preserved. Furthermore, the stainless steel construction is essential for cryogenic applications, where cold gas temperatures can affect the performance of lesser materials. This diaphragm ensures precise pressure control across the entire 0-200 PSI delivery range.

Operational efficiency is enhanced by the thoughtful design of the gauge and mounting system. The regulator features a back-mount inlet connection, which streamlines the geometry for connecting to liquid cylinders, keeping the setup compact and accessible. The large 2-1/2 inch single scale gauges are designed for high visibility, allowing technicians to monitor cylinder and delivery pressure from a greater distance than standard 2-inch gauges allow. With a maximum inlet pressure rating of 3500 PSI, this regulator is built to handle the pressures associated with bulk gas distribution safely and reliably.
