310-66250000 - Miller Smith 310 Silverline Stainless Steel Regulator, CGA 660, 0-25 PSIG

Technical Overview of the Miller Smith 310 Silverline Regulator

The Miller Smith 310-66-25-00-00 is a premium Single Stage High Purity Regulator from the Silverline series, engineered specifically for the precise control of corrosive, non-corrosive, and toxic gases in high-purity systems. The regulator is built on a foundation of 316 stainless steel bar stock, ensuring robust resistance to chemical attack and maintaining the integrity of the gas stream. A key technical feature is the 316 PCTFE seat, which is utilized for all wetted parts in corrosive applications, providing durability where standard materials would fail.

Precision pressure regulation is achieved through a specially designed convoluted stainless steel diaphragm. This diaphragm not only offers accurate response to pressure changes but also forms a metal-to-metal seal with the body, guaranteeing maximum leak integrity—a critical requirement for handling hazardous or high-purity media. The unit is capable of withstanding internal vacuum, making it suitable for purge cycles essential in maintaining system purity. The bonnet includes a captured 1/16-inch FNPT vent port, allowing for the safe piping and venting of hazardous gases in the unlikely event of a diaphragm failure.

This specific model features a CGA 660 stainless steel inlet connection and delivers a pressure range of 0-25 PSIG. It is equipped with a 1/4-inch MNPT needle valve on the outlet for fine flow control. The large 2-1/2 inch gauges provide clear readability of tank and delivery pressures. Designed for versatility, the bonnet is threaded for front panel mounting, and the body is tapped for rear panel mounting, facilitating integration into various instrumentation panels and gas delivery systems.
