OVERVIEW

Reliable Gas Delivery for Professional Applications

When your work demands precise gas regulation for hydrogen, methane, or other specialty gases utilizing a CGA 350 connection, the Miller Smith 621-20-06-00-00 Silverline Regulator is the professional's choice. Built by one of the most trusted names in the industry, this regulator combines rugged durability with laboratory-grade precision. The two-stage design is a game-changer for professionals who need consistent flow; it automatically compensates for the drop in cylinder pressure as you work, ensuring that your torch flame or process flow remains steady from the start of the tank to the bottom.

Built for Purity and Performance

The Silverline series stands out with its high-purity brass construction, finished with nickel plating for a clean, professional look and added durability. Inside, a stainless steel diaphragm provides the sensitivity needed for accurate pressure adjustments between 0 and 60 PSI. This metal diaphragm is far superior to standard rubber versions, offering a longer lifespan and ensuring that no impurities are introduced into your gas line. This makes it an excellent choice not just for welding, but for any application where gas purity is critical.

Safety You Can Trust

Handling combustible gases like hydrogen requires equipment that prioritizes safety. This Miller Smith regulator is equipped with capturable vents, allowing you to pipe potential leaks away from the work area, adding an extra layer of protection for you and your facility. The unit also features a high-quality filtered seat that prevents debris from entering the regulator, reducing maintenance needs and preventing unexpected failures. The 1/4" MNPT needle valve outlet provides precise flow control capabilities right out of the box.

Why Choose the 620 Silverline?

Investing in a high-quality regulator saves time and money in the long run. The stability provided by the two-stage mechanism means less time adjusting knobs and more time focusing on your work. With a massive 3500 PSI max inlet rating, it is compatible with a wide range of high-pressure cylinders. Backed by Miller's reputation for quality, this regulator is a solid investment for any shop, lab, or industrial site requiring CGA 350 gas service.

FAQ

The CGA 350 fitting is standard for Hydrogen, Methane, Carbon Monoxide, and Ethylene, among other flammable gas mixtures.

A two-stage regulator reduces pressure in two steps, providing a constant delivery pressure even as the cylinder pressure drops. A single-stage regulator's outlet pressure may drift as the tank empties.

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

It features a capturable vent in the bonnet (1/16" FNPT) which acts as a safety relief and allows hazardous gases to be piped away safely.

The delivery pressure range for this model is 0-60 PSI.

Yes, the regulator features threaded front and rear bonnets specifically designed for panel mounting.

The diaphragm is made of stainless steel, which ensures high purity and prevents gas contamination.

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