221-0009 - Miller Smith 220 Series Silverline High Purity Two-Stage Regulator CGA 580

Miller Smith Silverline: High Purity Performance

When your work demands absolute precision and cleanliness, the Miller Smith 221-00-09 Silverline High Purity Regulator delivers. Designed for professionals working with specialty gases, this two-stage regulator ensures that your gas flow remains consistent and pure, regardless of cylinder pressure fluctuations. Whether you are setting up a gas chromatography lab, managing calibration mixtures, or simply need the most stable flow possible for TIG welding critical components, this regulator provides the control you need. It connects via a standard CGA 580 fitting, making it compatible with Argon, Nitrogen, and Helium cylinders.

Consistent Pressure Delivery

One of the biggest challenges with standard regulators is the fluctuation in outlet pressure as the tank empties. The Miller Smith 221-00-09 solves this with its two-stage architecture. By stepping down the pressure in two phases, it isolates the delivery pressure from the changes in the tank, giving you a steady 0-60 PSIG output from the first crack of the valve until the tank is ready for change-out. This eliminates the need for constant manual adjustments and ensures your process remains stable.

Built for Longevity and Cleanliness

Contamination is the enemy of high-purity applications. That is why this regulator features a stainless steel diaphragm, which offers superior chemical resistance and eliminates the risk of rubber contamination in your gas line. A filtered seat adds an extra layer of protection, catching debris before it can damage the regulator's internal seal. The exterior is just as impressive, featuring a fully plated body and bonnet that resists corrosion and looks great in any shop or lab environment.

User-Friendly Features

Miller has equipped this unit with large, 2-1/2 inch gauges that are easy to read at a glance, allowing you to monitor both tank level and delivery pressure with ease. The 1/4 inch FNPT outlet allows for versatile connection options to your downstream equipment. With a max inlet rating of 3500 PSI and a built-in safety relief valve, you can operate with confidence knowing your equipment is protected. Upgrade to the Silverline series for a regulator that matches the high standards of your work.
