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

Miller Smith Silverline 223-84-06: The Standard for High Purity Regulation

When precision cannot be compromised, the Miller Smith 223-84-06 Silverline Two-Stage Regulator delivers the performance required for high-stakes analytical work. This regulator is part of the renowned 220 Silverline Series, designed specifically for controlling high purity gases and mixtures in laboratory settings. The two-stage architecture is the defining feature of this unit, offering a distinct advantage over single-stage alternatives. By reducing pressure in two steps, it eliminates the "decay" effect, ensuring that your delivery pressure remains rock-steady even as your gas cylinder drains. This stability is crucial for sensitive equipment like gas chromatographs, where pressure variances can skew results.

Built for Cleanliness and Accuracy

Contamination is the enemy of analytical accuracy. That is why the 223-84-06 features a stainless steel diaphragm. This material choice prevents the absorption of gases and subsequent outgassing that can occur with rubber diaphragms, ensuring that the gas reaching your instruments is as pure as the gas in the cylinder. The entire exterior—body, bonnet, and gauges—is nickel-plated, providing a clean, durable finish that resists environmental corrosion and maintains a professional appearance in laboratory setups. Inside, a filtered seat mechanism works to block debris, protecting the internal components and ensuring a long operational life.

Specifications and Safety

This model comes equipped with a CGA 350 inlet connection, typically used for gases such as Hydrogen, Carbon Monoxide, and Methane mixtures. It supports a maximum inlet pressure of 3500 PSIG and offers a delivery pressure range of 0-200 PSIG, adjustable via a smooth-turning control knob. The outlet is a 9/16-18 Left Hand connection, adhering to safety standards for fuel gases. An automatic reseating safety relief valve is built-in, providing peace of mind by venting excess pressure if necessary. The large, clear gauges make monitoring easy, reducing the risk of reading errors.

Ideal Applications

The Miller Smith 223-84-06 is recommended for a variety of high-precision applications. It is perfectly suited for controlling carrier gases for thermal conductivity and flame ionization detectors. It is also robust enough to withstand vacuums generated during purging cycles. If your operation demands constant pressure and uncompromised purity, this Silverline regulator is the professional's choice for reliable gas delivery.
