610-03050000 - Miller Smith 610 Series High Purity Regulator, CGA 346, 0-25 PSI

Precision Control for High Purity Applications

The Miller Smith 610-03-05-00-00 Silverline High Purity Brass Single Stage Regulator is engineered specifically for analytical and high-purity gas systems where contamination control is paramount. Designed to handle non-corrosive gases such as high-purity air (via CGA 346 connection), this regulator bridges the gap between standard industrial equipment and expensive ultra-high purity stainless steel units. By utilizing a brass bar stock body that is nickel-plated, it offers the cleanliness required for laboratory environments without the premium cost of full stainless steel construction.

Advanced Diaphragm Technology

At the heart of the 610 Series is a specially designed stainless steel diaphragm. Unlike elastomeric diaphragms that can absorb and release contaminants (off-gassing), the stainless steel construction ensures the integrity of the gas stream is maintained. This metal-to-metal seal between the body and the diaphragm eliminates the need for soft seals that could degrade over time or introduce impurities. This design provides maximum accuracy and stable regulation of delivery pressure, even as the cylinder pressure decays.

Contamination Prevention

Every aspect of the Silverline 610 Series is built to protect your process. The regulator features a filtered seat for added gas stream purity and includes a 316 stainless steel filter to trap any particulate matter before it enters the critical seating area. The unit is also capable of withstanding an internal vacuum, making it suitable for purge cycles often required in high-purity setups. Additionally, the bonnet includes a 1/16" FNPT port to capture and vent hazardous gases in the unlikely event of a diaphragm failure, enhancing safety in enclosed laboratory spaces.

Versatile Mounting and Usage

This model offers a delivery range of 0-25 PSI, making it ideal for low-pressure applications requiring fine adjustment. The regulator is designed with a threaded bonnet for easy panel mounting and the body is tapped for rear panel mounting, offering flexibility for integration into gas management panels or instrument benches. With a maximum inlet pressure rating of 3500 PSI, it is robust enough to handle high-pressure cylinders directly.
