620-20060000 - Miller Smith 620 Series High Purity 2-Stage Regulator CGA 350

Reliable Gas Delivery for Industrial Specialists

When your operation deals with specialty gases like Hydrogen or Methane, safety and precision are not optional—they are requirements. The Miller Smith 620 Series Silverline Regulator provides industrial-grade reliability in a high-purity package. This two-stage regulator is built to handle inlet pressures up to 3500 PSI while delivering a smooth, consistent low-pressure output of up to 25 PSI. The two-stage mechanism is particularly beneficial for long-duration processes, as it maintains a steady flame or flow rate without fluctuation, even as your gas cylinder pressure drops.

Durability is a key feature of the Silverline series. The body is machined from solid brass bar stock and finished with nickel plating, providing a rugged exterior that resists wear and corrosion in tough shop environments. The internal components are equally robust, featuring a stainless steel diaphragm that offers superior service life compared to rubber alternatives. This metal diaphragm also provides maximum sensitivity, allowing for fine-tuned pressure adjustments necessary for delicate heating or brazing applications involving high-energy gases.

Safety is built into every aspect of the design. The regulator includes a filtered seat to catch debris before it can damage the sealing surface, preventing creep and potential failure. It also features threaded front and rear bonnets, making it easy to panel mount for fixed installations. The inclusion of a capturable vent port allows you to pipe vented gases to a safe location, a critical feature when working with flammable gases like Hydrogen. Whether you are setting up a laser cutting station, a specialized brazing outfit, or a research test bench, the Miller Smith 620-20-06-00-00 delivers the performance and peace of mind professional welders and technicians demand.
