123-8208 - Miller Smith Silverline 2-Stage Oxygen Regulator, 0-250 PSI, CGA 540

Precision Control with Miller Smith Silverline Series

The Miller Smith 123-82-08 Silverline Series General Purpose Two-Stage Regulator is engineered for applications requiring unwavering delivery pressure and robust construction. As a two-stage regulator, this unit reduces cylinder pressure in two distinct steps, ensuring that the working pressure remains constant even as the cylinder pressure decays. This feature is critical for laboratory, testing, and precision industrial applications where pressure drift cannot be tolerated. The regulator is configured with a CGA 540 inlet connection, making it specifically suitable for Oxygen service, despite the general series description covering various inert gases.

Constructed from rugged brass bar stock, the body and bonnet are finished with a high-quality nickel plating. This plating not only provides a clean, professional aesthetic suitable for laboratory environments but also offers superior protection against corrosion and wear compared to raw brass. The internal mechanism features a large 1-7/8 inch diaphragm, which provides exceptional sensitivity and precise control over the delivery pressure range of 0-250 PSI. This specific pressure range is ideal for higher-pressure applications that exceed standard cutting torch requirements, offering versatility for various pneumatic and process needs.

Reliability is central to the Silverline design. The regulator incorporates Miller Smith's Sure-Seat technology, which utilizes a filtered seat to prevent debris from entering the high-pressure seating area. This significantly reduces the risk of seat failure and creep, extending the service life of the component. The unit is equipped with two large, 2-1/2 inch single-scale gauges that are easy to read, allowing operators to monitor both cylinder contents and delivery pressure at a glance. With a maximum inlet pressure rating of 3500 PSI, this regulator is compatible with standard high-pressure oxygen cylinders found in industrial and medical facilities.

Please note that while the Silverline series is often used for inert gases, this specific SKU (123-82-08) is outfitted with a CGA 540 fitting and 9/16"-18 RH outlet, designating it for Oxygen use. It is designed for non-hazardous environments and features a preset safety relief valve that vents to the atmosphere.
