614-03090000 - Miller Smith Silverline High Purity Regulator, 0-500 PSI, CGA 580, 1/4 Tube Outlet

Precision Control for High Purity Applications

The Miller Smith 614-03-09-00-00 Silverline High Purity Brass Single Stage Regulator is engineered to meet the rigorous demands of analytical laboratories, specialty gas delivery systems, and high-precision industrial processes. Part of the renowned 610 Silverline Series, this regulator is specifically designed to prevent contamination within high purity systems while providing accurate and stable regulation of non-corrosive gases. Its construction features a brass nickel-plated bar stock body, which offers superior durability and resistance to environmental factors compared to standard forged bodies.

Advanced Contamination Prevention

Central to the performance of this regulator is its 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 from inlet to outlet. The design utilizes a metal-to-metal seal between the body and the diaphragm, eliminating the need for gaskets that could degrade over time. Furthermore, a 316 stainless steel filter is integrated into the inlet to trap particulates, and a filtered seat design provides an additional layer of protection for gas stream purity.

Safety and Versatility

Safety is paramount in high-pressure gas handling. The Miller Smith 614-03-09-00-00 is capable of withstanding an internal vacuum and features a threaded bonnet with a capturable vent (1/16" FNPT). This allows hazardous or displaced gases to be piped away safely in the event of a diaphragm failure. The unit is equipped with a diffusion-resistant, packless diaphragm outlet valve, ensuring that the system remains closed to the atmosphere when not in use. With a delivery range of 0-500 PSIG and a maximum inlet pressure of 3500 PSIG, this regulator is versatile enough for a wide range of pneumatic and analytical applications. It is also designed for flexibility in installation, featuring a body tapped for rear panel mounting and a threaded bonnet for front panel mounting.
