312-00000000 - Miller Smith 310 Series Silverline Stainless Steel High Purity Regulator 0-100 PSIG

Precision Control for High Purity Applications

The Miller Smith 312-00-00-00-00 Silverline High Purity Regulator is a premier solution designed for the rigorous demands of analytical laboratories, semiconductor manufacturing, and specialty gas management. Part of the esteemed 310 Silverline Series, this single-stage regulator is engineered to maintain the integrity of high-purity systems while providing accurate regulation of corrosive, non-corrosive, or toxic gases. The unit features a delivery pressure range of 0-100 PSIG, making it ideal for applications requiring precise low-to-medium pressure control from high-pressure sources up to 3500 PSIG.

Material Excellence and Corrosion Resistance

When handling reactive or corrosive media, material compatibility is paramount. This regulator is constructed with a 316 stainless steel bar stock body and a 316 stainless steel filtered seat. These materials are specifically chosen to resist chemical attack, ensuring an extended service life and preventing contamination of the gas stream. All wetted parts—components exposed to the flowing media—are made from 316 stainless steel or PCTFE, providing a robust barrier against corrosion. This construction allows the regulator to be used confidently with a wide spectrum of specialty gases without the risk of material degradation.

Advanced Diaphragm Technology

At the heart of the 312-00-00-00-00 is a specially designed, convoluted stainless steel diaphragm. Unlike flat diaphragms, the convoluted design offers superior sensitivity and response to pressure changes, resulting in maximum accuracy and stable regulation of delivery pressure. The diaphragm employs a metal-to-metal seal with the body, a critical feature that ensures maximum leak integrity. This design eliminates the need for elastomeric seals in the diaphragm assembly, which can be sources of outgassing or permeation, thereby maintaining the strict purity levels required in analytical workflows.

Safety and Versatility

Safety is engineered into every aspect of the Silverline series. The regulator includes a captured vent port (1/16” FNPT) located in the bonnet. In the unlikely event of a diaphragm failure, this port allows for the safe piping and venting of hazardous gases away from the operator and workspace. Furthermore, the regulator is capable of withstanding an internal vacuum, making it compatible with purge cycles essential for maintaining system purity during cylinder changes. With 1/4" FNPT inlet and outlet connections, this unit offers versatile integration into panel mounts or line systems, supported by a bonnet threaded for front panel mounting and a body tapped for rear mounting.
