311-83230000 - Miller Smith 310 Series Silverline Stainless Steel Regulator, CGA 350, 0-50 PSIG

Technical Overview of the Miller Smith 310 Silverline Series

The Miller Smith 311-83-23-00-00 is a premium component within the 310 Silverline Series, engineered specifically for the rigorous demands of high purity and specialty gas regulation. This single-stage regulator is constructed from 316 stainless steel bar stock, ensuring compatibility with corrosive, non-corrosive, and toxic gases. The unit features a CGA 350 inlet connection and delivers a precise pressure range of 0-50 PSIG, making it ideal for analytical instrumentation and process control applications where gas purity is paramount.

At the core of this regulator's performance is its convoluted stainless steel diaphragm, which provides superior sensitivity and pressure stability compared to standard flat diaphragms. The design incorporates a metal-to-metal diaphragm seal, eliminating the need for elastomeric seals that can degrade or outgas, thereby ensuring maximum leak integrity. The seat assembly utilizes 316 PCTFE, a material chosen for its chemical resistance and mechanical stability, further protected by a 316 stainless steel filter to prevent particulate contamination from compromising the seal.

Safety and integration are key aspects of the 311-83-23-00-00 design. The bonnet includes a captured vent port (1/16" FNPT), allowing for the safe piping of vented gases away from the operator in the event of a diaphragm failure—a critical feature when handling hazardous media. For system integration, the regulator offers versatile mounting options: the bonnet is threaded for front panel mounting, while the body is tapped for rear panel installation. Large 2-1/2 inch single scale gauges provide clear, immediate readouts of inlet and delivery pressures.
