310-70310000 - Miller Smith 310 Series High Purity Stainless Steel Regulator, CGA 705, 0-25 PSIG

Miller Smith 310 Silverline High Purity Stainless Steel Regulator

The Miller Smith 310-70-31-00-00 Silverline Series regulator is a premium single-stage gas control device engineered specifically for high purity, toxic, and corrosive gas applications. Designed to meet the rigorous demands of laboratory, analytical, and industrial specialty gas environments, this regulator features a body machined from 316 stainless steel bar stock. This construction ensures minimal particle generation and maximum resistance to chemical attack, making it an ideal choice for maintaining the integrity of high-grade gas streams.

At the heart of the 310 Series is a specially designed convoluted stainless steel diaphragm. Unlike standard flat diaphragms, this convoluted design offers superior sensitivity and response to pressure changes, providing precise control over the delivery pressure range of 0-25 PSIG. The diaphragm utilizes a metal-to-metal seal with the body, eliminating the need for elastomeric seals that can degrade over time or introduce contaminants. This feature is critical for applications where leak integrity is paramount, ensuring that hazardous gases remain contained and process gases remain pure.

Safety is a cornerstone of the Miller Smith 310 design. 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 hazardous or toxic gases to be piped away to a safe ventilation system, protecting personnel and the facility. The seat assembly is constructed from 316 PCTFE, a material chosen for its excellent mechanical properties and resistance to corrosive media. This ensures an extended service life even when regulating aggressive gases.

The unit comes equipped with large, 2-1/2 inch single-scale gauges that are easy to read, allowing operators to monitor inlet and delivery pressures at a glance. The regulator is also versatile in its mounting options, featuring a threaded bonnet for front panel installation and tapped body holes for rear panel mounting. With a maximum inlet pressure rating of 3500 PSIG and a CGA 705 stainless steel connection, this regulator is ready for demanding service with ammonia and other compatible corrosive gases.
