310-66310000 - Miller Smith 310 Series Silverline SS Regulator, 0-25 PSIG, CGA 705

High Purity Stainless Steel Regulation

The Miller Smith 310-66-31-00-00 Silverline Regulator is a premium single-stage gas control device engineered specifically for high purity, toxic, and corrosive gas applications. Built from 316 stainless steel bar stock, this regulator is designed to withstand the harsh nature of corrosive media while maintaining the integrity of the gas stream. The internal architecture features a 316 PCTFE (Polychlorotrifluoroethylene) filtered seat, which is critical for preventing contamination and ensuring a long operational life even under challenging conditions.

Precision is paramount in specialty gas delivery. The 310 Series utilizes a convoluted stainless steel diaphragm that offers superior sensitivity and stable pressure regulation compared to standard flat diaphragms. This design allows for accurate control within the 0-25 PSIG delivery range. A metal-to-metal diaphragm seal eliminates the need for elastomeric seals that could outgas or degrade, thereby ensuring maximum leak integrity—a non-negotiable requirement for high purity systems.

Safety and versatility are integrated into the design. The regulator includes a captured vent port (1/16" FNPT) located in the bonnet, allowing operators to pipe hazardous fumes away safely in the rare event of a diaphragm failure. The unit is also capable of withstanding internal vacuum, making it suitable for purge cycles essential in maintaining system purity. With a maximum inlet pressure of 3500 PSIG and a CGA 705 connection, this regulator is the professional choice for analytical laboratories, petrochemical processing, and semiconductor manufacturing.
