622-00100000 - Miller Smith 620 Series Silverline High Purity Regulator CGA 590

Precision Control for High Purity Applications

The Miller Smith 622-00-10-00-00 Silverline High Purity Brass Two Stage Regulator is engineered to meet the rigorous demands of analytical laboratories, specialty gas delivery systems, and industrial processes requiring uncompromising gas purity. As part of the renowned 620 Silverline Series, this regulator is specifically designed for non-corrosive gases where maintaining the integrity of the gas stream is paramount. The unit features a robust nickel-plated brass bar stock body which not only provides a professional aesthetic but also offers enhanced resistance to environmental corrosion compared to standard forged bodies.

At the heart of this regulator is a specially designed stainless steel diaphragm. Unlike elastomeric diaphragms that can off-gas or absorb impurities, the stainless steel construction ensures that the gas stream remains uncontaminated during regulation. This is critical for applications such as gas chromatography, emission monitoring, and laser gas systems where even trace impurities can skew results or damage sensitive equipment. The metal-to-metal seal between the body and the diaphragm further reinforces this purity by eliminating the need for gaskets that could degrade over time.

The two-stage design of the 622-00-10-00-00 offers significant operational advantages over single-stage alternatives. By reducing the cylinder pressure in two steps, the regulator is able to provide a constant, unwavering outlet pressure even as the supply cylinder drains. This "flat" delivery characteristic is essential for long-duration processes where pressure drift could compromise quality. Additionally, the regulator includes a filtered seat to trap particulate matter, protecting the internal mechanism and ensuring a long service life. Safety is also addressed with a capturable vent in the bonnet (1/16" FNPT), allowing users to pipe vented gases away from the work area if necessary.

Equipped with a CGA 590 connection, this model is suitable for specific industrial air and specialty gas cylinders. The large 2-1/2 inch single scale gauge provides clear, readable pressure data at a glance. With a maximum inlet pressure of 3500 PSI and a delivery range up to 100 PSI, the Miller Smith Silverline regulator stands as a top-tier choice for professionals demanding precision, reliability, and purity in their gas regulation equipment.
