OVERVIEW

Miller Smith 222-42-09: The Standard for High Purity Gas Delivery

When your work involves sensitive analytical instruments, the quality of your gas delivery system is just as important as the gas itself. The Miller Smith 222-42-09 Silverline Regulator is a premium two-stage regulator designed to meet the rigorous demands of gas chromatography and other high-purity applications. Unlike standard industrial regulators, the Silverline series focuses on maintaining the integrity of the gas stream while providing unwavering pressure control. The two-stage mechanism is the hero here, providing a steady output pressure of 0-100 PSI without the "droop" or rise often seen in single-stage regulators as the supply cylinder empties.

Durability meets laboratory precision in the construction of this unit. The body is machined from solid brass bar stock and then finished with high-quality plating. This protects the regulator from external wear and keeps it looking clean in a professional lab environment. Inside, a stainless steel diaphragm reacts instantly to pressure changes, offering sensitivity that rubber or neoprene diaphragms cannot match. This metal diaphragm also ensures that no off-gassing or contamination enters your process stream, preserving the purity of your carrier gases or calibration mixtures.

The 222-42-09 is user-friendly and safe. It features large, clear 2-1/2 inch gauges that make checking tank levels and output settings simple. The CGA 580 inlet connection is standard for inert gases, making it compatible with Argon, Nitrogen, and Helium cylinders. For added control, this model includes a chrome-plated stainless steel needle valve on the outlet, giving you precise command over flow rates right out of the box. An automatic reseating safety relief valve is built-in, providing peace of mind by protecting against pressure spikes.

Backed by Miller's reputation for quality, this regulator is the smart choice for professionals running thermal conductivity detectors, flame ionization detectors, or simply needing reliable inert gas regulation. Invest in the Miller Smith Silverline series for equipment that performs as precisely as you do.

FAQ

A two-stage regulator reduces cylinder pressure in two steps, which allows it to maintain a constant delivery pressure even as the pressure in the supply cylinder drops. This is critical for analytical applications where pressure stability is required.

The CGA 580 connection is the standard fitting for inert gases, including Argon, Nitrogen, and Helium.

A stainless steel diaphragm is non-permeable and does not off-gas, ensuring the purity of the gas stream. It also provides more precise pressure control compared to elastomeric diaphragms.

This specific model (222-42-09) is configured for a delivery pressure range of 0-100 PSI.

No, the 220 Silverline series is recommended for high purity, non-corrosive gases. Corrosive gases require regulators made of specific materials like stainless steel or Monel throughout the wetted path.

Yes, this model includes a 1/8" tube stainless steel needle valve (chrome plated) on the outlet for fine flow control.

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

Yes, the design allows it to withstand vacuums generated during purging operations without damaging the internal components.
