Miller Smith 310 Silverline Stainless Steel Regulator, 100 PSIG, CGA 705

Industrial Grade Stainless Steel Regulator

The Miller Smith 310 Series Silverline Regulator (Model 312-66-31-00-00) represents the gold standard in single-stage regulation for industrial and specialty gas applications. Built to withstand the challenges of corrosive environments, this regulator is constructed from high-grade 316 stainless steel bar stock. This material choice is not merely for durability; it is essential for preventing chemical reactions with corrosive gases that would otherwise degrade standard brass regulators. Whether you are managing ammonia or other specialty gases requiring a CGA 705 connection, this regulator delivers the reliability and safety required for heavy-duty industrial use.

Precision and control are achieved through a sophisticated convoluted stainless steel diaphragm. This component is engineered to provide maximum accuracy in pressure regulation, smoothing out fluctuations and delivering a steady 0-100 PSIG output. The metal-to-metal seal between the diaphragm and the body eliminates the need for gaskets that could leak or degrade, ensuring maximum leak integrity. This is particularly critical in industrial settings where gas leaks can lead to costly downtime, safety hazards, or environmental compliance issues. The regulator's seat is made from 316 PCTFE, a material chosen for its hardness and chemical resistance, ensuring a tight seal and long operational life.

Operational safety and versatility are key features of the Miller Smith 312-66-31-00-00. The unit features a captured vent port in the bonnet, a critical safety feature that allows for the containment and diversion of hazardous gases should the diaphragm be compromised. This makes the regulator suitable for use in enclosed spaces or gas cabinets where venting to the atmosphere is not an option. Furthermore, the regulator is designed to support system purging, capable of withstanding internal vacuum conditions without damage. This allows operators to effectively remove air and moisture from the system during cylinder changes, maintaining the integrity of the process gas.

Designed for the professional, the regulator includes large 2-1/2 inch gauges that are easy to read from a distance, reducing the risk of reading errors. The versatile mounting options—threaded bonnet for front panel and tapped body for rear panel—make it adaptable to a wide range of system configurations. Whether installed on a cylinder or integrated into a manifold system, the Miller Smith Silverline regulator provides the consistent performance and rugged durability expected by welding and industrial gas professionals.
