623-00080000 - Miller Smith Silverline 620 Series High Purity Oxygen Regulator, 2-Stage, 0-250 PSI

Precision Control for High Purity Applications

The Miller Smith 623-00-08-00-00 Silverline High Purity Brass Two Stage Regulator is engineered for professionals who demand exacting standards in gas delivery. Designed specifically for non-corrosive specialty gases, this regulator is a staple in laboratory and high-precision industrial environments where gas purity and pressure stability are paramount. The Silverline 620 Series distinguishes itself with a robust nickel-plated brass bar stock body, offering both durability and resistance to environmental corrosion.

Uncompromised Gas Purity

At the heart of this regulator is a specially designed stainless steel diaphragm. Unlike elastomeric diaphragms that can outgas or absorb contaminants, the stainless steel construction ensures that the gas stream remains pure from the cylinder to your application. This is further reinforced by a metal-to-metal body-to-diaphragm seal, eliminating the need for gaskets that could compromise system integrity. A 316 stainless steel filter and a filtered seat design provide additional layers of protection, trapping particulates and ensuring that only clean gas reaches your sensitive equipment.

Stable Two-Stage Performance

As a two-stage regulator, the 623-00-08-00-00 excels in maintaining a constant outlet pressure of 0-250 PSI, regardless of fluctuations in the inlet pressure. This means that as your oxygen cylinder depletes from its maximum 3500 PSI capacity, the delivery pressure remains rock-steady, removing the need for constant manual adjustments. This feature is critical for analytical instruments and processes where pressure variance can lead to inaccurate results or process failures.

Safety and Versatility

Safety is built into the design with captured 1/16" FNPT vent ports on the bonnet, allowing for the safe piping away of gases in the unlikely event of a diaphragm failure. The regulator is also capable of withstanding internal vacuums, making it suitable for purging operations. With threaded front and rear bonnets, this unit is ready for panel mounting, offering versatile installation options for custom gas manifolds and systems.
