113-4009 - Miller Smith Silverline 113-40-09 Inert Gas Regulator 250 PSI CGA 580

Technical Overview: Miller Smith 113-40-09 Silverline Regulator

The Miller Smith 113-40-09 is a robust single-stage regulator from the Silverline Series, engineered for general purpose applications involving inert and non-corrosive gases such as Air, Nitrogen, CO2, and Argon. This unit is specifically configured with a CGA 580 inlet connection and provides a delivery pressure range of 0-250 PSIG, making it suitable for a variety of industrial and laboratory tasks where extremely precise low-pressure control is not the primary requirement, but reliability and durability are paramount.

Constructed from rugged brass bar stock, the body is designed to withstand the rigors of industrial environments. The regulator features a plated body, bonnet, and gauges, offering superior protection against external corrosion and wear. Internally, the unit utilizes a large 1-7/8 inch diaphragm which facilitates precise pressure control across the delivery range. A key technical feature is the filtered seat design, which prevents particulate contamination from entering the seating area, thereby ensuring gas stream purity and significantly extending the service life of the regulator.

The 113-40-09 is rated for a maximum inlet pressure of 3500 PSIG. It includes large, easy-to-read 2-1/2 inch single scale gauges that allow operators to monitor cylinder and delivery pressure at a glance. The body is also tapped for rear panel mounting, providing flexibility for installation in gas manifolds or custom panels. With Sure-Seat technology, this regulator minimizes maintenance downtime and ensures consistent performance for inert gas management.
