320-00000000 - Miller Smith 320 Series High Purity Two-Stage Stainless Steel Regulator, 0-25 PSI

High Purity Precision for Critical Applications

The Miller Smith 320 Series High Purity Two-Stage Regulator is engineered for the most demanding gas delivery applications where purity, corrosion resistance, and pressure stability are non-negotiable. Designed specifically for analytical instrumentation, petrochemical processing, and laboratory research, this regulator features a robust 316 Stainless Steel bar stock body and a convoluted stainless steel diaphragm. This construction ensures compatibility with a wide range of corrosive and non-corrosive gases, preventing contamination of the gas stream and degradation of the regulator components over time.

The two-stage reduction mechanism is a critical feature for applications requiring consistent delivery pressure. Unlike single-stage regulators, the 320 Series compensates for the drop in cylinder pressure as the gas is consumed, maintaining a steady 0-25 PSI output without the need for constant manual adjustment. This stability is essential for sensitive equipment where pressure fluctuations can lead to erroneous readings or process failures.

Advanced Safety and Design Features

Safety and integrity are paramount in the design of the 320 Series. The regulator utilizes a metal-to-metal diaphragm seal, providing maximum leak integrity which is crucial when handling hazardous or expensive specialty gases. Furthermore, the bonnet features captured vent ports (1/16" FNPT), allowing users to pipe hazardous gases away to a safe ventilation system in the rare event of a diaphragm failure. The unit is also designed to withstand internal vacuums, making it suitable for rigorous purging operations required during cylinder changes.

Equipped with large, easy-to-read 2-1/2 inch single scale gauges, operators can quickly monitor both inlet and delivery pressures. The 316 stainless steel filtered seat adds another layer of protection, trapping particulates to maintain gas purity and extend the service life of the seat assembly. With a maximum inlet pressure rating of 3500 PSI and 1/4" FNPT connections, this regulator is a versatile solution for high-purity gas management systems.
