210-0000 - Miller Smith 210 Series High Purity Analytical Regulator, 0-15 PSI, 1/4" FNPT

Technical Overview of the Miller Smith 210 Silverline Regulator

The Miller Smith 210-00-00 Silverline High Purity Analytical Single Stage Regulator is a precision-engineered instrument designed specifically for the control of high purity, non-corrosive gases. This unit is part of the renowned 210 Silverline series, which bridges the gap between standard industrial regulators and ultra-high purity instrumentation. The core of this regulator's performance lies in its stainless steel diaphragm. Unlike elastomeric diaphragms which can absorb and release contaminants (off-gassing) or allow atmospheric diffusion, the stainless steel construction provides a hermetic seal that preserves the integrity of the gas stream. This feature is critical for analytical applications where even trace levels of contamination can skew results.

The regulator operates with a delivery pressure range of 0-15 PSIG, making it ideal for low-pressure applications requiring stability and fine adjustment. It is rated for a maximum inlet pressure of 3500 PSIG. The body and bonnet are machined from rugged brass bar stock and then plated. This plating not only provides an aesthetic finish suitable for laboratory environments but also offers superior protection against external corrosion and wear. Internally, the regulator features a filtered seat. This design element is crucial for maintaining gas purity and protecting the seating surface from microscopic particulates that could cause leaks or creep over time.

Connectivity is provided via 1/4" FNPT ports on both the inlet and outlet, allowing for versatile integration into custom gas delivery systems, manifolds, or direct cylinder connections using appropriate CGA fittings (sold separately). The unit is also designed to withstand vacuums, a necessary feature for systems that undergo vacuum purging cycles to eliminate atmospheric air before introducing process gases. A built-in capturable preset safety relief valve adds a layer of protection for downstream equipment. The body is tapped to facilitate rear panel mounting, ensuring secure installation in instrument benches or control panels.
