622-00070000 - Miller Smith 620 Series Silverline High Purity Two-Stage Regulator CGA 510

Precision Control for High Purity Applications

The Miller Smith 622-00-07-00-00 Silverline High Purity Brass Two Stage Regulator is engineered for professionals who demand exacting standards in gas delivery. Part of the renowned 620 Silverline Series, this regulator is specifically designed for non-corrosive specialty gases where maintaining gas purity and stable pressure is critical. The unit features a robust nickel-plated brass bar stock body, which not only provides a professional aesthetic but also ensures long-lasting durability and resistance to environmental corrosion.

Advanced Diaphragm Technology

At the heart of this regulator is a specially designed stainless steel diaphragm. Unlike traditional rubber or neoprene diaphragms, stainless steel does not absorb or release contaminants, ensuring that the purity of your gas stream is maintained from the cylinder to your instrument. The metal-to-metal seal between the body and the diaphragm further eliminates the risk of leakage and outgassing, a common issue with elastomeric seals. This construction allows the regulator to withstand internal vacuums during purging operations, making it highly suitable for analytical laboratories and process control applications.

Stable Two-Stage Performance

The two-stage design of the 622-00-07-00-00 provides a significant operational advantage: constant outlet pressure. As a gas cylinder empties, the inlet pressure drops, which can cause single-stage regulators to exhibit a rise in delivery pressure (decay). This two-stage system compensates for inlet fluctuations, delivering a steady 0-100 PSI output throughout the life of the cylinder. This stability is essential for sensitive equipment where pressure variances can skew results or damage components.

Safety and Versatility

Safety is paramount in high-purity environments. This model includes capturable vents in the bonnet (1/16" FNPT), allowing users to pipe vented gases away to a safe location in the event of a diaphragm failure. The regulator also features a 316 stainless steel filter to protect the seat from particulate damage. With a CGA 510 connection, it is compatible with standard fuel gas cylinders such as Propane and Acetylene, provided they are of the appropriate purity grade for the application.
