211-4005 - Miller Smith 210 Silverline High Purity Air Regulator, CGA 346, 0-60 PSI

Precision Control for Analytical Applications

The Miller Smith 211-40-05 Silverline High Purity Analytical Single Stage Regulator is engineered to meet the exacting demands of laboratory and analytical environments. Part of the renowned 210 Silverline Series, this regulator is specifically designed for non-corrosive, high-purity gas applications where maintaining the integrity of the gas stream is paramount. With a CGA 346 inlet connection, it is optimized for use with high-purity air and compatible gas mixtures, supporting a maximum inlet pressure of 3500 PSIG and providing a delivery pressure range of 0-60 PSIG.

Superior Materials and Construction

Construction quality is a hallmark of the Silverline series. The 211-40-05 features a stainless steel diaphragm, which is critical for preventing off-gassing and ensuring that the regulator itself does not introduce contaminants into the process stream. This metal diaphragm also provides a stable delivery pressure, resisting the fluctuations often seen with elastomeric diaphragms. The body, bonnet, and gauges are machined from rugged brass bar stock and then fully plated. This plating not only provides an aesthetic finish but offers superior protection against environmental corrosion and wear, ensuring a long service life even in busy chemical process plants or automotive testing facilities.

Advanced Design Features

To further ensure gas purity, the regulator incorporates a filtered seat. This feature traps microscopic particles that might otherwise damage the seat or contaminate downstream instrumentation, thereby extending the maintenance intervals and overall life of the unit. The regulator is also designed to withstand vacuums generated during purging operations, a common requirement in high-purity setups to eliminate atmospheric contamination before gas flow begins. For facility integration, the body is tapped to allow for rear panel mounting, making it ideal for installation in gas cabinets or analytical benches. Large, 2-1/2 inch single-scale gauges allow operators to monitor cylinder and delivery pressure with ease and accuracy.
