321-83220000 - Miller Smith 320 Silverline High Purity Stainless Steel Regulator, CGA 330, 50 PSI

Precision Control for High Purity Applications

The Miller Smith 321-83-22-00-00 is a premium component of the 320 Silverline Series, engineered specifically for the rigorous demands of high purity and corrosive gas regulation. Designed for environments where contamination is unacceptable and precision is paramount, this two-stage regulator ensures a stable delivery pressure of 0-50 PSIG regardless of fluctuations in the cylinder's inlet pressure. Its construction is centered around a 316 stainless steel bar stock body, providing a robust defense against corrosive media that would degrade standard brass regulators.

Advanced Material Engineering

Every wetted part within this regulator is crafted from materials selected for their chemical inertness and durability. The seat is a 316 stainless steel filtered assembly, which not only extends the service life of the unit but also acts as a critical barrier against particulate contamination in the gas stream. Complementing this is a convoluted stainless steel diaphragm that offers superior sensitivity to pressure changes while maintaining a metal-to-metal seal. This sealing method is vital for achieving maximum leak integrity, ensuring that hazardous or expensive specialty gases remain contained within the system.

Safety and Versatility

Safety in handling hazardous gases is a core design principle of the 321-83-22-00-00. The regulator features captured vent ports (1/16" FNPT) in the bonnet, allowing operators to pipe vented gases away to a safe location in the rare event of a diaphragm failure. Furthermore, the unit is designed to withstand internal vacuums, making it compatible with purging operations essential for maintaining system purity during cylinder changes. With a CGA 330 inlet and a 1/4" tube fitting outlet, this regulator is ready for integration into sophisticated gas delivery manifolds and analytical setups.
