223-8406 - Miller Smith Silverline 220 Series High Purity Two-Stage Regulator CGA 350

Precision Control for Analytical Applications

The Miller Smith 223-84-06 Silverline High Purity Analytical Two-Stage Regulator is engineered to meet the rigorous demands of laboratory and analytical environments. Designed specifically for high purity, non-corrosive pure gases and mixtures, this regulator ensures that critical applications such as gas chromatography receive a stable and contaminant-free gas supply. The unit features a robust two-stage design, which is essential for maintaining constant delivery pressure regardless of fluctuations in the cylinder pressure. As the cylinder empties, single-stage regulators can experience a rise in delivery pressure, but the Silverline 220 Series compensates for this, providing a steady flow from full to nearly empty cylinders.

Superior Materials and Construction

Constructed from rugged brass bar stock, the body, bonnet, and gauges are fully plated with nickel to offer superior protection against corrosion and to maintain the cleanliness required for high-purity applications. A key feature of this model is its stainless steel diaphragm. Unlike elastomeric diaphragms that can absorb and release contaminants (outgassing), the stainless steel diaphragm ensures precise pressure control without compromising the purity of the gas stream. This makes it ideally suited for controlling carrier gases or calibration mixtures used in thermal conductivity, flame ionization, flame photometry, and electron capture detectors.

Enhanced Safety and Durability

Safety and longevity are built into the core of the 223-84-06. The regulator includes a built-in capturable preset safety relief valve that protects components from over-pressurization. Additionally, a filtered seat is integrated into the design to trap particulates, adding another layer of gas stream purity and significantly extending the service life of the seat assembly. The large 2-1/2 inch single scale gauges are easy to read, allowing operators to monitor cylinder and delivery pressure at a glance. With a maximum inlet pressure of 3500 PSIG and a delivery range of 0-200 PSIG, this regulator is a versatile tool for professionals requiring exacting standards.

Reliable Performance in Critical Settings

Whether used for purging operations where vacuums are generated or for steady-state flow in analytical instruments, the Miller Smith Silverline regulator stands up to the task. Its CGA 350 connection is standard for flammable gases like Hydrogen and Methane (check specific gas compatibility), and the left-hand thread outlet (9/16-18 LH) ensures proper safety connections. Trust in the reliability of Miller Smith's engineering to deliver consistent performance in your most critical gas delivery systems.
