310-83250000 - Miller Smith 310 Series High Purity Stainless Steel Regulator, 0-25 PSIG, CGA 660

Precision Control for High Purity Applications

The Miller Smith 310-83-25-00-00 Silverline High Purity Regulator is a premium-grade instrument engineered for the rigorous demands of specialty gas delivery. Designed specifically for systems requiring the utmost cleanliness and corrosion resistance, this single-stage regulator is constructed from 316 stainless steel bar stock. It is the ideal solution for controlling corrosive, non-corrosive, and toxic gases in laboratory, analytical, and industrial environments where contamination must be eliminated.

Advanced Material Construction

At the core of the 310 Series is its robust material composition. All wetted parts are manufactured from 316 PCTFE (Polychlorotrifluoroethylene) and 316 stainless steel. This specific combination provides exceptional resistance to chemical attack, ensuring the regulator maintains its integrity even when exposed to harsh media. The seat is filtered to protect against particulate damage, extending the service life of the unit and maintaining gas stream purity.

Leak Integrity and Safety

Safety and precision are paramount in high-purity applications. The regulator features a convoluted stainless steel diaphragm that offers sensitive pressure response and stable regulation. Crucially, the diaphragm utilizes a metal-to-metal seal, eliminating the need for elastomeric seals that can degrade or outgas, thereby maximizing leak integrity. For applications involving hazardous gases, the bonnet includes a captured 1/16-inch FNPT vent port, allowing for the safe piping and venting of gases in the unlikely event of a diaphragm failure.

Versatile Mounting and Operation

The 310-83-25-00-00 is designed for versatility. It supports a delivery pressure range of 0-25 PSIG and can handle inlet pressures up to 3500 PSIG. The unit is equipped with large, easy-to-read 2-1/2 inch single scale gauges. Installation is flexible, with a threaded bonnet for front panel mounting and a tapped body for rear panel mounting. This regulator is an essential component for any high-purity gas distribution system requiring CGA 660 connectivity.
