OVERVIEW

Precision Control for Analytical Applications

The Miller Smith 223-20-08 Silverline High Purity Analytical Two-Stage Regulator is engineered for applications demanding the highest levels of precision and gas purity. Part of the renowned 220 Silverline Series, this regulator features a rugged brass bar stock construction that is fully plated—including the body, bonnet, and gauges—to provide superior protection against environmental corrosion and to maintain a clean aesthetic suitable for laboratory environments.

At the core of this regulator is a stainless steel diaphragm which provides sensitive and accurate pressure control, essential for analytical instrumentation. The two-stage design is a critical feature for users requiring unwavering delivery pressure; it automatically compensates for the drop in cylinder pressure as the gas is consumed, ensuring that the output remains stable from a full cylinder down to nearly empty. This eliminates the need for constant manual adjustments during long operational cycles.

The unit is equipped with a CGA 540 inlet connection, making it suitable for high-purity oxygen and compatible specialty gas mixtures. It delivers a pressure range of 0-150 PSIG, monitored via large, easy-to-read 2-1/2 inch single scale gauges. Additional safety and durability features include a built-in capturable preset safety relief valve and a filtered seat that protects the seating mechanism from particulate damage, extending the service life of the regulator. The inclusion of an outlet needle valve allows for fine flow control directly at the regulator.

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.
