110-4007 - Miller Smith Silverline 110 Series Regulator, CGA 510, 15 PSI Delivery

Technical Overview of the Miller Smith 110-40-07

The Miller Smith 110-40-07 is a distinguished member of the Silverline Series, designed specifically as a general-purpose single-stage regulator. Engineered for applications where extremely precise control of delivery pressure is not the primary requirement, this unit excels in providing reliable flow for inert and non-corrosive gases such as Air, Nitrogen, CO2, and Argon. Despite the standard association of CGA 510 fittings with fuel gases, this specific configuration is listed by the manufacturer for inert gas service, featuring a maximum inlet pressure rating of 3500 PSI and a delivery capacity tailored to 15 PSI applications.

Construction quality is a hallmark of the Silverline series. The 110-40-07 features a rugged brass body machined from bar stock, ensuring structural integrity and resistance to mechanical stress. To further enhance durability and resistance to environmental corrosion, the body, bonnet, and gauges are fully plated. The internal mechanism utilizes a large 1-7/8 inch diaphragm, which provides a significant surface area for pressure regulation, resulting in stable delivery pressure even as cylinder pressure decays. The regulator also incorporates Miller's Sure-Seat technology, a filtered seat design that protects the high-pressure seat from particulate contamination, thereby extending the service life of the component and maintaining gas stream purity.

This regulator is designed with versatility in mind. The body is tapped to accommodate rear panel mounting, making it suitable for fixed installations or custom manifold setups. The 2-1/2 inch single-scale gauges are designed for high visibility, allowing operators to monitor cylinder and delivery pressure at a glance. While not recommended for high-purity applications requiring minimal inboard diffusion or outgassing, the 110-40-07 stands as a robust solution for standard industrial MRO tasks, pneumatic testing, and general shielding gas delivery where a CGA 510 connection is utilized.
