320-68220000 - Miller Smith 320 Series High Purity Stainless Steel Two-Stage Regulator, CGA 330, 0-25 PSI

High Purity Pressure Control for Corrosive Environments

The Miller Smith 320-68-22-00-00 is a premium high-purity, two-stage regulator engineered specifically for the precise control of corrosive and non-corrosive gases. Part of the 320 Silverline Series, this regulator is constructed with wetted parts made entirely of 316 Stainless Steel and PCTFE, ensuring maximum resistance to corrosion and maintaining the purity of the gas stream. It is an essential component for laboratory, analytical, and industrial applications where gas integrity and precise delivery pressures are critical.

This model features a CGA 330 inlet connection, typically used for corrosive gases, and provides a delivery pressure range of 0-25 PSI. The two-stage design is a key technical advantage, as it provides a constant delivery pressure regardless of fluctuations in the inlet pressure, such as when a gas cylinder is being depleted. This stability is achieved through a convoluted stainless steel diaphragm that offers superior sensitivity and control compared to standard flat diaphragms.

Safety and leak integrity are paramount in the design of the 320 Series. The regulator utilizes a metal-to-metal diaphragm seal, which provides a high level of leak integrity necessary for handling hazardous or high-purity gases. Additionally, the bonnet features a captured vent port (1/16" FNPT), allowing users to pipe vented gases away to a safe location in the event of a diaphragm failure. The unit is also designed to withstand internal vacuums, making it suitable for purging operations essential in high-purity gas handling.
