OVERVIEW

Reliable Delivery for Critical Applications

When your work involves specialty gases like Hydrogen or Methane, standard industrial regulators simply won't cut it. The Miller Smith 622-83-06-00-00 Silverline Regulator is built to deliver the consistency and safety you need. Whether you are running a gas chromatograph, a process analyzer, or a specialized welding setup requiring high-purity shielding gas, this regulator ensures your equipment receives a steady flow at the exact pressure you set.

Why Choose Two-Stage?

If you've ever experienced the frustration of having to constantly tweak your regulator as your tank gets low, you'll appreciate the two-stage design of the Silverline series. By stepping down the pressure twice, it isolates your delivery line from the changes happening in the tank. You get a smooth, flat line of pressure from a full tank all the way down to empty. This reliability allows you to focus on your task, not your equipment.

Built for the Long Haul

Miller Smith is synonymous with quality, and the Silverline series is no exception. The nickel-plated brass body resists corrosion and wear, while the stainless steel diaphragm offers maximum sensitivity and longevity. Unlike rubber diaphragms that can degrade or off-gas over time, the stainless steel construction maintains the purity of your gas, ensuring that your results aren't compromised by your equipment. The large 2-1/2 inch gauge makes reading your pressure settings easy, even from a distance.

Safety First

Handling flammable or specialty gases requires strict safety protocols. This regulator includes a captured vent port, allowing you to pipe any potential leaks to a safe exhaust system—a crucial feature for indoor or laboratory environments. Combined with its ability to handle purge vacuums, the Miller Smith 622-83-06-00-00 gives you complete control over your gas delivery system safely and effectively.

FAQ

The CGA 350 fitting is typically used for flammable gases such as Hydrogen, Methane, Carbon Monoxide, and Ethylene. Always verify your cylinder valve type before connecting.

A two-stage regulator provides constant outlet pressure even as the cylinder pressure decreases. This eliminates the need for frequent readjustment and ensures consistent flow throughout the life of the cylinder.

No, the Miller Smith 620 Silverline series is designed for non-corrosive high-purity gases. For corrosive applications, a stainless steel body regulator would be required.

This regulator is rated for a maximum inlet pressure of 3500 PSI.

Yes, it features threaded front and rear bonnets specifically designed to facilitate panel mounting.

The capturable vent (1/16" FNPT) allows you to connect a tube to pipe away gases to a safe location in the event of a diaphragm failure, which is critical when using hazardous or flammable gases.

The diaphragm is constructed from stainless steel, which provides maximum accuracy, stability, and prevents contamination of the gas stream.

Yes, the design is capable of withstanding internal vacuums, making it suitable for purging operations required in high-purity systems.
