OVERVIEW

Miller Smith 320 Silverline Series: The Standard for Stainless Steel Regulators

When your work environment demands equipment that can withstand corrosive elements while delivering unwavering precision, the Miller Smith 322-00-21-00-00 Two-Stage Regulator is the professional's choice. Part of the renowned 320 Silverline Series, this regulator is built to provide constant delivery pressure regardless of inlet pressure fluctuations, making it a workhorse for industrial and specialty gas applications.

The robust construction features a body machined from 316 stainless steel bar stock, ensuring high corrosion resistance and durability in harsh environments. Unlike standard brass regulators, this stainless steel unit is compatible with a wider range of specialty gases, including those that are corrosive. It comes equipped with a CGA 326 connection and standard 1/4" FNPT outlet, making it versatile for various system integrations. The large, 2-1/2 inch single-scale gauges are easy to read, allowing operators to monitor tank and delivery pressure at a glance.

Miller Smith has prioritized operational safety and longevity in this design. The regulator includes a filtered seat to protect the valve mechanism from particulates, extending the service life of the unit. The convoluted stainless steel diaphragm offers precise pressure control, while the captured vent ports provide a necessary safety layer for venting hazardous gases. Whether you are setting up a new process line or replacing aging equipment, this regulator delivers the quality and reliability backed by the Miller True Blue Warranty.

FAQ

A two-stage regulator reduces cylinder pressure in two steps, providing a constant delivery pressure even as the cylinder pressure drops. A single-stage regulator's delivery pressure may fluctuate as the cylinder empties.

CGA 326 is typically used for specific corrosive or high-purity gas mixtures, often including Nitrous Oxide in stainless steel applications. Always verify compatibility with your gas supplier.

Yes, the 322 series is constructed with 316 Stainless Steel and PCTFE wetted parts, making it suitable for many corrosive gases.

The maximum inlet pressure rating for this regulator is 3500 PSIG.

For hazardous gas applications, a Cross Purge Assembly is highly recommended to ensure effective purging of gas traces during cylinder changes.

The captured vent ports (1/16" FNPT) in the bonnet allow you to pipe vented gases to a safe location in the event of a diaphragm failure, which is critical for hazardous gas safety.

Yes, the front and rear bonnets are threaded to accommodate front panel mounting.

This model (322-00-21-00-00) has a delivery pressure range of 0-100 PSIG.
