123-2006 - Miller Smith Silverline 120 Series 2-Stage Regulator CGA 350 250 PSI

Precision Two-Stage Gas Control

The Miller Smith 123-20-06 Silverline Series Regulator is a premium two-stage gas control device designed for applications requiring unwavering delivery pressure. Unlike single-stage regulators that may allow delivery pressure to rise as the supply cylinder drains (a phenomenon known as the decaying inlet characteristic), this two-stage unit compensates for inlet pressure changes automatically. This makes it an exceptional choice for laboratories, testing facilities, and precision maintenance shops where consistency is critical. The unit is engineered with a CGA 350 inlet connection and is capable of delivering pressures up to 250 PSIG, making it versatile for a variety of industrial setups.

Rugged Construction and Reliability

Durability is at the core of the Silverline Series. The body is machined from solid brass bar stock, providing a dense, robust housing that resists damage from physical impact and workplace wear. To further enhance longevity, the body, bonnet, and gauges are plated, offering superior protection against corrosion and environmental degradation. Inside, the regulator features Miller's proprietary Sure-Seat technology. This filtered seat design prevents microscopic debris from entering the seating area, which is the most common cause of regulator failure. By filtering the gas stream, the regulator maintains high purity and extends the service interval significantly.

User-Friendly Design

Operators will appreciate the large, easy-to-read 2-1/2 inch single scale gauges that allow for quick monitoring of both cylinder and delivery pressures. The pressure adjustment is managed via a large 1-7/8 inch diaphragm, which provides sensitive and accurate control over the output. The regulator also includes a preset safety relief valve that vents to the atmosphere, adding a layer of safety for personnel and equipment. Designed for versatility, the body is tapped to accommodate rear panel mounting, allowing for clean and organized installation in gas manifolds or control panels.
