313-70240000 - Miller Smith 310 Silverline Stainless Steel Regulator, CGA 580, 0-250 PSIG

Technical Overview of the Miller Smith 310 Silverline Series

The Miller Smith 313-70-24-00-00 is a premium component within the 310 Silverline Series, engineered specifically for high-purity, corrosion-resistant applications. This single-stage regulator is meticulously constructed to handle the rigorous demands of specialty gas delivery, including corrosive, non-corrosive, and toxic gases. The core of its design philosophy centers on material integrity and contamination prevention. All wetted parts—components exposed to the flowing media—are manufactured from 316 Stainless Steel and PCTFE (Polychlorotrifluoroethylene). This specific metallurgy is chosen for its exceptional resistance to chemical attack and its ability to maintain a pristine gas path, ensuring that the purity of the source gas is preserved from the cylinder to the point of use.

Mechanically, the regulator features a convoluted stainless steel diaphragm. Unlike flat diaphragms, the convoluted design offers superior sensitivity and response to pressure changes, allowing for precise regulation of the delivery pressure within the 0-250 PSIG range. The diaphragm seal is a critical control point in high-purity systems; this model utilizes a metal-to-metal seal to achieve maximum leak integrity, effectively eliminating the outgassing or permeation issues often associated with elastomeric seals. This construction also allows the regulator to withstand internal vacuum, a necessary feature for systems that require evacuation or purging before use.

Safety and integration are also key technical attributes. The bonnet is equipped with a captured vent port (1/16" FNPT), which is essential for the safe piping and venting of hazardous gases in the event of a diaphragm failure. For system integration, the regulator offers versatile mounting options: the bonnet is threaded for front panel mounting, while the body is tapped for rear panel mounting. The unit is rated for a maximum inlet pressure of 3500 PSIG and connects via a CGA 580 fitting, making it suitable for a wide range of inert and specialty gas cylinders.
