312-85250000 - Miller Smith 310 Series Silverline SS Regulator, CGA 660, 0-100 PSIG

High Purity Precision for Corrosive Environments

The Miller Smith 312-85-25-00-00 Silverline High Purity Regulator is a premier solution designed specifically for the rigorous demands of specialty gas delivery. Engineered as part of the renowned 310 Silverline Series, this single-stage regulator is constructed to handle corrosive, non-corrosive, and toxic gases with exceptional safety and reliability. The core of its design features a body and filtered seat made from 316 Stainless Steel, ensuring that the gas stream remains uncontaminated and that the unit withstands the harsh nature of corrosive media. For applications requiring absolute purity, such as in laboratory settings, semiconductor manufacturing, or chemical processing, the material integrity of the regulator is paramount.

One of the standout technical features of this model is its convoluted stainless steel diaphragm. Unlike standard rubber or elastomer diaphragms, this metal diaphragm provides a metal-to-metal seal, which is critical for maintaining maximum leak integrity. This design eliminates the risk of off-gassing or permeation that can occur with softer materials, thereby preserving the high purity of the system. The convoluted shape allows for a high degree of sensitivity and precise control over the delivery pressure, which ranges from 0 to 100 PSIG in this specific configuration. This ensures that downstream equipment receives a stable and accurate flow of gas, even when working with sensitive instrumentation.

Safety is a central component of the 312-85-25-00-00's architecture. The regulator includes a captured vent port located in the bonnet, threaded with a 1/16" FNPT connection. In the unlikely event of a diaphragm failure, this port allows for the safe piping and venting of hazardous or toxic gases away from the work area, protecting personnel and the facility. Additionally, the regulator is equipped with large, 2-1/2 inch single-scale gauges that are easy to read, allowing operators to monitor cylinder and delivery pressure at a glance. With a maximum inlet pressure rating of 3500 PSIG and a CGA 660 connection tailored for specific corrosive gas cylinders, this Miller Smith regulator represents the gold standard in high-purity gas control.
