221-4005 - Miller Smith Silverline 220 Series Two-Stage Analytical Regulator, CGA 346, 0-50 PSI

Reliable High Purity Gas Regulation

When precision cannot be compromised, the Miller Smith 221-40-05 Silverline Regulator stands out as a top-tier choice for professionals. This high-purity, two-stage regulator is built to deliver consistent performance for specialty gas applications. Whether you are managing carrier gases for laboratory equipment or requiring stable pressure for sensitive industrial processes, the Silverline series provides the reliability associated with the Miller name. The unit features a CGA 346 inlet connection, making it compatible with specific compressed air and specialty gas cylinders, and offers a delivery pressure range of 0-50 PSIG.

Built for Durability and Readability

The construction of the 221-40-05 is designed for both longevity and ease of use. The body is machined from rugged brass bar stock, ensuring it can withstand the physical demands of a workspace. However, Miller goes a step further by plating the entire body, bonnet, and gauges. This plating not only gives the regulator a professional, clean appearance but also provides a layer of protection against corrosion and wear. The large, 2-1/2 inch gauges are easy to read, allowing operators to monitor cylinder and delivery pressure at a glance without squinting or guesswork. The single-scale design keeps readings simple and direct.

Consistent Performance

Fluctuating delivery pressures can ruin experiments and disrupt processes. The two-stage design of this Miller Smith regulator solves this problem by automatically compensating for the drop in cylinder pressure as gas is consumed. This means you set your pressure once, and the regulator maintains it until the tank is effectively empty. Coupled with a stainless steel diaphragm for precise pressure response and a filtered seat to prevent debris from damaging the internal components, this regulator is an investment in accuracy. It also includes an automatic reseating safety relief valve for added peace of mind.
