OVERVIEW

Reliable Gas Delivery with Miller Smith Quality

When your work depends on consistent gas flow and absolute purity, the Miller Smith 223-40-06 Silverline Regulator delivers. Built by one of the most trusted names in gas equipment, this two-stage regulator is designed to handle the rigorous demands of specialty gas delivery. Whether you are working with Hydrogen, Methane, or other gases requiring a CGA 350 connection, this regulator ensures that your downstream equipment receives a steady, unwavering flow, free from the pressure spikes and drops common with lesser equipment.

Consistent Pressure, Every Time

The primary advantage of the Silverline 220 Series is its two-stage architecture. For welders and technicians who have struggled with "end-of-cylinder" pressure drift, this regulator is the solution. It automatically compensates for the dropping pressure in your supply tank, maintaining your set delivery pressure until the cylinder is practically empty. This means less time adjusting knobs and more time focusing on your critical tasks. The stainless steel diaphragm adds another layer of precision, offering sensitive pressure control that rubber diaphragms simply cannot match.

Built to Last

Durability is woven into every aspect of the 223-40-06. The regulator features a rugged brass bar stock construction that is fully plated for corrosion resistance and durability. This plating not only looks good but protects the body and bonnet from the wear and tear of industrial environments. The gauges are large and clear, reducing eye strain and minimizing reading errors. Furthermore, the filtered seat design prevents microscopic debris from damaging the sealing surface, ensuring a long, leak-free service life.

Safety First

Miller Smith prioritizes safety with a built-in capturable preset safety relief valve. This feature provides peace of mind by protecting the regulator and downstream equipment from potential over-pressurization events. Compatible with CGA 350 cylinders, this regulator is the professional's choice for managing high-purity fuel gases and mixtures safely and efficiently. Upgrade to the Silverline series and experience the difference that precision engineering makes in your daily operations.

FAQ

The CGA 350 fitting is typically used for flammable gases such as Hydrogen, Methane, Carbon Monoxide, and Natural Gas, as well as certain high-purity mixtures.

A two-stage regulator provides constant delivery pressure regardless of changes in the inlet (cylinder) pressure. This is crucial for analytical applications where stable pressure is required as the cylinder empties.

A stainless steel diaphragm does not absorb or release contaminants like rubber diaphragms can, ensuring the purity of the gas stream. It also provides more precise pressure control.

No, this regulator is recommended for high purity, non-corrosive pure gases and mixtures. Corrosive gases require regulators made of specific materials like Monel or Stainless Steel bodies.

The Miller Smith 223-40-06 is rated for a maximum inlet pressure of 3500 PSI.

Yes, it features a built-in capturable preset safety relief valve to protect components from over-pressurization.

The regulator comes with a 1/4" FNPT (Female National Pipe Thread) outlet connection, often paired with a needle valve or tube fitting.

Yes, the design is capable of withstanding vacuums generated during purging operations without damage to the diaphragm or internal components.
