622-00000000 - Miller Smith 620 Silverline High Purity 2-Stage Regulator, 0-100 PSI, 1/4" FNPT

Precision Control for High Purity Applications

The Miller Smith 622-00-00-00-00 Silverline High Purity Brass Two Stage Regulator is engineered for professionals demanding 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 precise pressure control is paramount. The unit features a robust nickel-plated brass bar stock body, which not only provides durability but also offers diffusion resistance essential for maintaining system integrity.

At the heart of this regulator is a unique stainless steel diaphragm. Unlike elastomeric diaphragms, the stainless steel construction prevents off-gassing and permeation, ensuring that the gas stream remains uncontaminated. The metal-to-metal seal between the body and the diaphragm further enhances the leak-tight integrity of the device. A 316 stainless steel filter is integrated into the seat to trap particulates, protecting the internal components and ensuring added gas stream purity.

Functionally, the two-stage design is a critical advantage for analytical applications. It compensates for the drop in cylinder pressure as the gas is consumed, providing a constant delivery pressure of up to 100 PSI without the need for constant manual adjustment. The unit is equipped with 1/4" FNPT inlet and outlet connections, offering versatility for custom plumbing or panel mounting configurations. Safety is also addressed with capturable 1/16" FNPT vent ports in the bonnet, allowing for the safe venting of hazardous gases if a diaphragm failure were to occur. This regulator is also capable of withstanding internal vacuums, making it suitable for purging operations.
