313-66220000 - Miller Smith 310 Series Silverline SS Regulator, CGA 330, 250 PSIG

High Purity Corrosion Resistant Gas Control

The Miller Smith 313-66-22-00-00 Silverline Series Regulator is a premium single-stage pressure control device engineered specifically for high-purity and corrosive gas applications. Manufactured from high-grade 316 stainless steel bar stock, this regulator is designed to withstand the harsh chemical environments associated with specialty gases while maintaining exceptional cleanliness and leak integrity. The unit features a CGA 330 connection, making it suitable for a specific range of corrosive and inert gases often found in laboratory, pharmaceutical, and industrial chemical processes.

Advanced Diaphragm and Seat Technology

At the core of the 310 Silverline series is a specially designed convoluted stainless steel diaphragm. Unlike flat diaphragms, this convoluted design provides superior sensitivity and stable regulation of delivery pressure across the 0-250 PSIG range. The diaphragm utilizes a metal-to-metal seal with the body, eliminating the need for elastomeric seals that can degrade or outgas, thereby ensuring maximum leak integrity. Furthermore, the regulator incorporates a 316 PCTFE (Polychlorotrifluoroethylene) seat, which offers excellent chemical resistance and mechanical strength, ensuring a long service life even when controlling aggressive media.

Safety and Versatility

Safety is paramount when handling hazardous or toxic gases. The Miller Smith 313-66-22-00-00 includes a captured vent port (1/16" FNPT) located in the bonnet. This critical feature allows operators to pipe vented gases away to a safe disposal system in the unlikely event of a diaphragm failure, preventing exposure to personnel. The regulator is also designed for versatility in installation, featuring a threaded bonnet for front panel mounting and a tapped body for rear panel mounting. Whether integrated into a gas delivery panel or mounted directly to a cylinder, this regulator provides reliable, precise control for critical applications.

Technical Specifications

This model is rated for a maximum inlet pressure of 3500 PSIG and includes large, easy-to-read 2-1/2 inch gauges. The outlet is equipped with a 1/4" MNPT stainless steel needle valve, allowing for fine flow adjustment downstream. A 316 stainless steel filtered seat is standard, providing an added layer of protection against particulate contamination in the gas stream.
