311-66220000 - Miller Smith 310 Series Silverline SS Regulator, CGA 330, 0-50 PSIG

Technical Precision for High Purity Applications

The Miller Smith 311-66-22-00-00 Silverline High Purity Regulator is an elite instrument engineered for the rigorous demands of specialty gas delivery. Designed specifically for environments requiring the handling of corrosive, non-corrosive, or toxic gases, this single-stage regulator is built upon a foundation of 316 stainless steel bar stock. The choice of material is critical; 316 stainless steel provides superior resistance to chemical attack, ensuring that the regulator body maintains structural integrity and does not introduce contaminants into the gas stream. This model is configured with a CGA 330 inlet connection, making it suitable for a specific range of corrosive gases often utilized in laboratory and industrial synthesis applications.

At the heart of the 310 Series Silverline regulator is a convoluted stainless steel diaphragm. Unlike elastomeric diaphragms that can degrade or outgas, the stainless steel diaphragm offers a metal-to-metal seal, providing maximum leak integrity—a non-negotiable feature when handling hazardous media. The convoluted design enhances the sensitivity of the regulator, allowing for precise control of delivery pressure within the 0-50 PSIG range. Furthermore, the regulator features a 316 stainless steel filtered seat. This filtration is essential for protecting the seating surface from particulate damage, thereby extending the service life of the unit and maintaining the high purity of the gas stream.

Safety and integration are paramount in the design of the 311-66-22-00-00. The bonnet is equipped with a captured vent port (1/16" FNPT), which allows for the safe piping and venting of hazardous gases in the unlikely event of a diaphragm failure. This feature is critical for maintaining a safe working environment in enclosed laboratories or processing facilities. The unit also includes a stainless steel needle valve on the outlet (1/4" MNPT), providing operators with fine flow control immediately downstream of the pressure regulation. With a maximum inlet pressure rating of 3500 PSIG, this regulator is robust enough to handle high-pressure cylinders while delivering stable, low-pressure output.
