211-4009 - Miller Smith 210 Silverline High Purity Regulator, CGA 580, 0-60 PSI

Precision Control for Analytical Applications

The Miller Smith 211-40-09 Silverline High Purity Analytical Single Stage Regulator is a premium solution designed for environments where gas purity and precise pressure control are paramount. Engineered by Miller Smith, a leader in gas regulation technology, this unit is part of the renowned 210 Silverline Series. It is specifically constructed to handle high purity, non-corrosive gases, making it an ideal choice for sophisticated applications such as instrument analysis, biological laboratories, and chemical process plants. The regulator features a CGA 580 connection, suitable for inert gases like Nitrogen, Argon, and Helium, and offers a delivery pressure range of 0-60 PSI.

Superior Construction and Purity

One of the standout features of this regulator is its construction. The body is machined from rugged brass bar stock, which is then plated along with the bonnet and gauges. This plating offers superior protection against corrosion and wear, ensuring the unit maintains its integrity even in demanding environments. Crucially, the diaphragm is made from stainless steel. Unlike rubber or neoprene diaphragms, stainless steel does not off-gas or absorb contaminants, ensuring that the gas stream remains pure from the cylinder to the application. This resistance to inboard diffusion of atmospheric contamination is critical for analytical work where even trace impurities can skew results.

Reliability and Safety Features

The Miller Smith 211-40-09 is designed with operational safety and longevity in mind. It includes a filtered seat that traps particulates, protecting the internal mechanism and extending the service life of the regulator. The unit is also capable of withstanding vacuums generated during purging operations, a common procedure in high-purity setups. For safety, it incorporates a built-in capturable preset safety relief valve. The large, 2-1/2 inch single scale gauges are easy to read, allowing operators to monitor cylinder and delivery pressure with a quick glance. Additionally, the body is tapped for rear panel mounting, providing versatile installation options for custom gas manifolds or laboratory benches.
