310-85250000 - Miller Smith 310 Silverline High Purity Stainless Steel Regulator, 25 PSIG, CGA 660

High Purity Regulation for Corrosive Environments

The Miller Smith 310-85-25-00-00 Silverline High Purity Regulator is a premium single-stage regulator engineered specifically for the precise control of corrosive, non-corrosive, and toxic gases. Designed for high-purity systems where contamination control is critical, this regulator features a body machined from 316 stainless steel bar stock. This construction ensures robust resistance to corrosive media and maintains the integrity of the gas stream. The unit is equipped with a CGA 660 inlet connection, making it suitable for specific corrosive gas mixtures often found in laboratory and industrial applications.

Precision and Stability

At the heart of the 310 Series is a specially designed convoluted stainless steel diaphragm. Unlike standard flat diaphragms, this convoluted design offers superior sensitivity and accuracy, providing stable regulation of delivery pressure even as cylinder pressure decays. The diaphragm utilizes a metal-to-metal seal, eliminating the need for elastomeric seals that can outgas or degrade over time. This design feature provides maximum leak integrity, ensuring that high-purity requirements are met and maintained throughout the regulator's service life. The delivery pressure range is calibrated for 0-25 PSIG, allowing for fine-tuned low-pressure control.

Safety and Durability Features

Safety is paramount when handling hazardous gases. The Miller Smith 310 Series includes a captured vent port (1/16” FNPT) located in the bonnet. This allows users to pipe vented gases away to a safe disposal area in the unlikely event of a diaphragm failure. Additionally, the regulator features a 316 PCTFE seat, which is filtered to prevent particulate damage and ensure a positive shut-off. The regulator is also capable of withstanding an internal vacuum, making it compatible with purge cycles essential for maintaining system purity during cylinder changes. Large 2-1/2 inch single-scale gauges provide clear, easy-to-read pressure monitoring.
