OVERVIEW

Precision and Purity with Miller Smith Silverline

When your application demands the highest levels of purity and corrosion resistance, the Miller Smith 311-70-22-00-00 Silverline Regulator stands out as the professional's choice. Part of the renowned 310 Silverline Series, this single-stage regulator is meticulously crafted to handle the unique challenges of specialty gas delivery. Whether you are working in a laboratory setting, semiconductor manufacturing, or industrial chemical processing, this regulator provides the reliability and precision necessary for critical operations. With a delivery range of 0-50 PSIG and a CGA 330 stainless steel inlet, it is specifically configured for cylinders containing corrosive gases.

The construction of the Miller Smith 311-70-22-00-00 sets it apart from standard industrial regulators. It utilizes a 316 stainless steel filtered seat which not only extends the service life of the unit by trapping particulates but also ensures that the gas stream remains uncontaminated. The metal-to-metal diaphragm seal eliminates the use of elastomers that could outgas or degrade over time, thereby maintaining the strict purity standards required for analytical instrumentation. The large, 2-1/2 inch single scale gauges are easy to read, allowing operators to monitor cylinder and delivery pressure with a quick glance, enhancing operational efficiency and safety.

Designed for versatility and safety, this regulator is capable of handling a maximum inlet pressure of 3500 PSIG. It is equipped with a captured vent port in the bonnet, a standard feature for high-purity regulators handling hazardous gases, enabling the safe venting of gases away from the work area. The unit also supports the use of a Cross Purge Assembly (sold separately), which is highly recommended for corrosive applications to purge the system during cylinder change-outs, preventing atmospheric moisture from reacting with the process gas. Trust in the Miller Smith legacy of quality to provide a regulator that delivers consistent performance, safety, and durability.
