OVERVIEW

Reliable High Purity Gas Delivery

For professionals requiring exacting standards in gas delivery, the Miller Smith 221-40-02 Silverline Regulator stands out as a top-tier solution. While many regulators are built for general industrial use, this model is tailored for high-purity applications where consistency is not just desired, but required. If you are working with carrier gases or calibration mixtures for gas chromatography, thermal conductivity, or flame ionization, this regulator provides the stability you need to ensure accurate and repeatable results.

The primary advantage of this Miller Smith unit is its two-stage architecture. In many gas delivery scenarios, as a tank empties, the outlet pressure of a single-stage regulator can creep upwards, requiring constant manual adjustment. The 221-40-02 eliminates this issue by automatically compensating for dropping cylinder pressure, delivering a steady 0-50 PSIG output from start to finish. This

FAQ

A two-stage regulator reduces the cylinder pressure in two steps, which provides a constant delivery pressure regardless of changes in the inlet pressure as the cylinder empties. This is essential for analytical applications requiring high precision.

The CGA 320 connection is the standard fitting for Carbon Dioxide (CO2). This regulator is intended for high purity CO2 applications.

No, the Miller Smith 221-40-02 is recommended for high purity, non-corrosive pure gases and mixtures. Using it with corrosive gases can damage the internal components.

This regulator features a stainless steel diaphragm, which ensures precise pressure control and prevents contamination of the high-purity gas stream.

Yes, it includes a built-in capturable preset safety relief valve that automatically reseats to protect components from over-pressurization.

This model is designed for a delivery pressure range of approximately 0-50 PSIG, suitable for most analytical and laboratory applications.

Yes, the design allows the regulator to withstand vacuums generated during purging operations without damage.

This regulator is part of the Miller Smith 220 Silverline Series, known for its high purity analytical capabilities.
