311-83250000 - Miller Smith 310 Series Silverline SS Regulator CGA 660 50 PSIG

High Purity Control for Corrosive Environments

The Miller Smith 311-83-25-00-00 Silverline High Purity Regulator is a premium single-stage gas regulation solution designed specifically for the rigorous demands of specialty gas applications. Engineered to maintain the integrity of high-purity systems, this regulator is constructed almost entirely from 316 stainless steel, ensuring compatibility with corrosive, non-corrosive, and toxic gases. Whether used in analytical laboratories, semiconductor manufacturing, or chemical processing, the Silverline series delivers reliability where contamination control is critical.

At the heart of this regulator is a convoluted stainless steel diaphragm that provides exceptional sensitivity and precise control over delivery pressure. Unlike standard rubber diaphragms, the stainless steel construction prevents off-gassing and permeation, preserving the purity of the gas stream. The metal-to-metal diaphragm seal further enhances leak integrity, a vital feature when handling hazardous media. Additionally, the regulator features a 316 PCTFE filtered seat, which offers superior resistance to corrosion and extends the service life of the unit even under harsh operating conditions.

Safety is a primary focus of the 310 Series design. The bonnet includes a captured vent port (1/16" FNPT), allowing users to pipe vented gases away to a safe location in the event of a diaphragm failure—a mandatory requirement for toxic gas handling. With a maximum inlet pressure of 3500 PSIG and a delivery range of 0-50 PSIG, this regulator offers the versatility needed for precise low-pressure applications. The unit comes equipped with large 2-1/2 inch gauges for easy reading and is tapped for rear panel mounting, making it a versatile choice for custom gas delivery systems.
