OVERVIEW

Reliable High Purity Gas Delivery

For professionals in laboratory settings or industries requiring analytical-grade gas delivery, the Miller Smith 223-20-08 Silverline Regulator is the standard for reliability. Designed specifically for high purity, non-corrosive gases, this regulator is the ideal choice for controlling carrier gases or calibration mixtures used in gas chromatography, including thermal conductivity, flame ionization, and electron capture applications.

The primary advantage of this unit is its two-stage capability. Unlike single-stage regulators that show a 'decaying' delivery pressure as the supply tank empties, this Miller Smith regulator maintains a constant output pressure throughout the life of the cylinder. This stability is paramount when running sensitive analytical tests where pressure fluctuations could invalidate results. The regulator is also robust enough to withstand vacuums generated during purging operations, ensuring versatility in complex gas setups.

Durability meets precision with its plated construction and stainless steel diaphragm. The plating ensures the unit remains free from oxidation and contamination, while the stainless diaphragm prevents off-gassing or absorption that could compromise the purity of the gas stream. With a max inlet rating of 3500 PSI and a delivery range up to 150 PSI, it handles standard high-pressure cylinders with ease. Whether for a research lab or a quality control facility, the 223-20-08 provides the consistent performance required for critical tasks.

FAQ

A two-stage regulator reduces the 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 essential for analytical applications requiring stable flow.

CGA 540 is the standard connection for Oxygen. In high purity applications, it is used for pure oxygen or specific gas mixtures compatible with this fitting.

No, this regulator is recommended for high purity, non-corrosive pure gases and mixtures. Corrosive gases require regulators made of different materials like stainless steel or Monel.

This specific model (223-20-08) is rated for a delivery pressure range of 0-150 PSIG.

Yes, it features a built-in capturable preset safety relief valve to protect components from over-pressurization.

The diaphragm is made of stainless steel, which provides precise control and prevents contamination of the gas stream.

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

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