212-0003 - Miller Smith 210 Silverline High Purity Regulator, CGA 326, 0-100 PSI

Precision Control for Analytical Applications

The Miller Smith 212-00-03 Silverline High Purity Analytical Single Stage Regulator is engineered to meet the rigorous demands of laboratory and industrial analytical environments. Designed specifically for non-corrosive specialty gases, this regulator ensures that the integrity of your gas stream remains uncompromised from the cylinder to the instrument. The core of its performance lies in the stainless steel diaphragm, which provides a non-contaminating surface and precise pressure regulation, eliminating the off-gassing or absorption issues often associated with elastomeric diaphragms.

Constructed from rugged brass bar stock, the entire body, bonnet, and gauge casings are fully plated. This plating offers superior protection against environmental corrosion and maintains a clean, professional appearance suitable for laboratory settings. The regulator features a CGA 326 inlet connection and delivers a consistent pressure range of 0-100 PSIG, making it ideal for applications requiring stable, low-to-medium pressure delivery. The unit is rated for a maximum inlet pressure of 3500 PSIG, ensuring compatibility with high-pressure cylinders.

Operational safety and longevity are paramount in the Silverline 210 Series. The regulator includes a built-in capturable preset safety relief valve to protect downstream equipment. Additionally, a filtered seat mechanism prevents particulate contamination, significantly extending the service life of the seat and ensuring reliable shut-off performance. The design is highly resistant to inboard diffusion of atmospheric contaminants and is robust enough to withstand vacuums generated during purging operations, a critical feature for maintaining high-purity standards.

User convenience is addressed with large, 2-1/2 inch single-scale gauges that are easy to read at a glance. The body is also tapped for rear panel mounting, providing flexibility for installation in gas cabinets or instrument benches. Whether used for automotive emissions testing, biological research, or chemical process control, the Miller Smith 212-00-03 delivers the reliability and purity required for critical tasks.
