OVERVIEW

Reliable Two-Stage Performance for the Shop

When your work demands consistency, the Miller Smith 122-20-09 Silverline Series Regulator delivers. This general-purpose two-stage regulator is a workhorse for welders and fabricators using inert gases like Argon and Nitrogen. Unlike single-stage regulators that can allow delivery pressure to creep up as your tank empties, this two-stage unit maintains a steady flow from start to finish. This means you spend less time tweaking your settings and more time focused on the job at hand. Whether you are purging piping, pressure testing, or running pneumatic tools, the 0-100 PSI range gives you the versatility needed for a wide variety of shop tasks.

Durability is a hallmark of the Silverline series. The regulator is machined from solid brass bar stock and finished with a protective plating that resists corrosion and stands up to the bumps and scrapes of daily shop use. The internal components are protected by a filtered seat that prevents debris from damaging the sealing surface, ensuring a long operational life and reducing maintenance costs. The large 2-1/2 inch gauges are clear and easy to read, even from a distance, so you always know your pressure status.

This model comes equipped with a CGA 580 inlet, the standard connection for Argon, Nitrogen, and Helium tanks. The outlet features a 1/4" Male NPT connection with a needle valve, providing fine control over the flow rate right at the regulator. It is an ideal choice for maintenance shops, testing benches, and general fabrication areas where reliable, non-corrosive gas control is required. Trust in Miller Smith's Sure-Seat technology and robust construction to keep your operations running smoothly.

FAQ

A two-stage regulator, like the 122-20-09, reduces cylinder pressure in two steps. This maintains a constant delivery pressure even as the cylinder pressure drops, whereas a single-stage regulator may require adjustment as the tank empties.

The CGA 580 fitting is the standard connection for inert gases including Argon, Nitrogen, and Helium.

This specific model (122-20-09) has a delivery pressure range of 0-100 PSIG.

While the regulator internals are compatible with CO2, the CGA 580 inlet does not fit standard CO2 cylinders (which use CGA 320). An adapter would be required, but it is generally recommended to use a regulator with the correct native fitting.

Yes, it includes a preset safety relief valve that vents to the atmosphere, suitable for non-hazardous gases.

The regulator is rated for a maximum inlet pressure of 3500 PSIG.

No, this regulator is designed for inert and non-corrosive gases only. Corrosive gases require stainless steel or Monel construction.

It features a 1/4" Male NPT outlet equipped with a needle valve for flow control.
