OVERVIEW

Unmatched Control for Analytical Work

When your work involves sensitive laboratory equipment or gas chromatography, standard industrial regulators simply don't cut it. The Miller Smith 221-03-02 Silverline Regulator is built to deliver the consistent, contaminant-free performance required for high-stakes analytical environments. Designed for use with Carbon Dioxide (CGA 320), this regulator takes the guesswork out of gas delivery, allowing you to focus on your results rather than your equipment.

Consistent Delivery Pressure

One of the biggest challenges with gas cylinders is the fluctuation in delivery pressure as the tank empties. The 221-03-02 solves this with its premium two-stage design. By stepping down the pressure in two phases, it maintains a rock-steady output of 0-50 PSI regardless of whether your cylinder is full or nearing replacement. This means you won't have to constantly adjust the knob to maintain your required flow, ensuring your experiments or processes run smoothly from start to finish.

Built for Purity and Durability

Contamination can ruin sensitive instruments. That's why this Miller Smith regulator features a stainless steel diaphragm that preserves the purity of your gas stream. Combined with a filtered seat, it blocks impurities and prevents the regulator materials themselves from affecting your gas quality. The exterior is just as robust, featuring a plated body and bonnet that resist corrosion and wear, ensuring the tool looks and performs like new for years. The large, easy-to-read gauges make monitoring your levels simple, even from a distance.

Reliable Safety Features

Miller Electric has integrated essential safety features directly into the 221-03-02. An automatic reseating safety relief valve protects the internal components from pressure spikes, while the rugged brass bar stock construction ensures the unit can handle the rigors of daily use. Whether you are purging systems with a vacuum or running long-duration tests, this regulator provides the reliability and safety professional technicians trust.

FAQ

The regulator is equipped with a CGA 320 inlet connection, which is the standard standard for Carbon Dioxide (CO2) cylinders.

A stainless steel diaphragm is non-permeable and does not off-gas, ensuring that the high purity of the gas stream is maintained without contamination from the regulator itself.

A two-stage regulator provides constant delivery pressure regardless of fluctuations in the cylinder pressure, eliminating the need for frequent readjustment as the cylinder empties.

This model has a delivery pressure range of 0-50 PSIG (often listed as 0-60 on gauges), suitable for low-pressure analytical applications.

No, the 220 Silverline series is recommended for high purity, non-corrosive pure gases and mixtures. It is not designed for corrosive service.

Yes, these regulators are designed to withstand vacuums generated during purging operations, which is critical for maintaining system purity.

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

While it is durable, it is designed for analytical and high-purity applications. Standard industrial welding regulators are typically more cost-effective for general welding, whereas this is precision equipment.
