323-85220000 - Miller Smith 320 Series High Purity Stainless Steel Regulator, CGA 330, 250 PSI

Precision Control for High Purity Applications

The Miller Smith 323-85-22-00-00 is a premium high-purity two-stage regulator from the distinguished 320 Silverline Series, engineered specifically for the precise control of corrosive and non-corrosive specialty gases. Constructed from 316 stainless steel bar stock, this regulator ensures maximum corrosion resistance and gas stream purity, making it ideal for analytical instrumentation, process control, and laboratory applications where contamination must be strictly eliminated. The two-stage design provides exceptional delivery pressure stability, maintaining a constant 0-250 PSIG output even as the cylinder pressure decays, which is critical for long-duration protocols and sensitive equipment.

Advanced Structural Integrity

Key structural features include a convoluted stainless steel diaphragm that offers precise pressure regulation and a metal-to-metal diaphragm seal that ensures high leak integrity, rated for demanding environments. The unit is equipped with a 316 stainless steel filtered seat to prevent particulate damage and extend service life, ensuring long-term reliability. Safety is paramount with captured vent ports (1/16" FNPT) on the bonnet, allowing for the safe piping of hazardous fumes in the event of a diaphragm failure. The regulator is also designed to withstand internal vacuums, making it suitable for purging operations essential in high-purity gas handling.

Specifications and Connectivity

This model features a CGA 330 inlet connection, specifically designed for use with certain corrosive gases, and is rated for a maximum inlet pressure of 3500 PSI. The large 2-1/2 inch single-scale gauges provide clear and immediate pressure readings. Additionally, the front and rear bonnets are threaded, facilitating easy front panel mounting for integrated system setups. Whether for chromatography, EPA protocol gases, or laser gas systems, the Miller Smith 323-85-22-00-00 delivers the performance and safety required by industry professionals.
