212-2005 - Miller Smith Silverline 210 Series High Purity Air Regulator CGA 346

High Purity Analytical Control

The Miller Smith 212-20-05 Silverline High Purity Analytical Single Stage Regulator is engineered for applications demanding strict gas purity and precise pressure control. Designed specifically for non-corrosive gases, this regulator features a CGA 346 connection, making it the standard choice for high-purity air applications in laboratory and industrial settings. The core of its performance lies in the stainless steel diaphragm. Unlike elastomeric diaphragms that can absorb and release contaminants, the stainless steel construction ensures that the gas stream remains unadulterated, preserving the integrity of sensitive analytical instruments.

Constructed from rugged brass bar stock, the entire body, bonnet, and gauge casings are plated to provide superior protection against environmental corrosion and to maintain a clean, professional appearance suitable for laboratory environments. The regulator is equipped with a filtered seat that not only enhances gas purity by trapping particulates but also significantly extends the service life of the seat mechanism. With a maximum inlet pressure of 3500 PSI and a delivery range of 0-100 PSI, it offers versatile performance for a variety of pneumatic requirements.

Operational safety and ease of use are paramount in the Silverline series. The unit includes a built-in capturable preset safety relief valve, adding a layer of protection against over-pressurization. The large 2-1/2 inch gauges are designed with a single scale for clear, unambiguous readings, reducing the risk of operator error. Additionally, the body is tapped for rear panel mounting, allowing for clean, integrated installation in gas cabinets or instrument benches. This regulator is an optimal solution for automotive emissions testing, biological laboratories, and chemical process plants where brass construction is compatible.
