The Miller Smith 310 Series Silverline High Purity Regulator is engineered to meet the rigorous demands of analytical laboratories and specialty gas management. Designed specifically for preventing contamination in high-purity systems, this single-stage regulator provides accurate and stable regulation for corrosive, non-corrosive, and toxic gases. The core of its performance lies in its construction; the body is machined from 316 stainless steel bar stock, ensuring robust resistance to chemical attack and structural integrity under pressure.
Critical to its operation is the convoluted stainless steel diaphragm. Unlike flat diaphragms, this convoluted design offers superior sensitivity and response to pressure changes, minimizing hysteresis and ensuring a stable delivery pressure even as the cylinder decays. The diaphragm utilizes a metal-to-metal seal, eliminating the need for elastomeric seals that can outgas or degrade over time, thereby guaranteeing maximum leak integrity essential for maintaining gas purity levels. For applications involving corrosive media, all wetted parts—including the seat—are constructed from 316 PCTFE and stainless steel.
Safety and versatility are paramount in the 310 Series design. The bonnet features a captured vent port (1/16" FNPT), allowing operators to pipe hazardous fumes away to a safe scrubbing or ventilation system in the rare event of a diaphragm failure. The unit is also capable of withstanding an internal vacuum, making it suitable for purge cycles and vacuum applications down to 30" HG. With a delivery range of 0-30 PSIG (and vacuum capability), this regulator is perfectly suited for precise low-pressure applications requiring absolute cleanliness.
