614-00000000 - Miller Smith Silverline 610 Series High Purity Regulator, 0-500 PSI, 1/4" FNPT

Technical Overview: Miller Smith 610 Series Silverline Regulator

The Miller Smith 614-00-00-00-00 is a premium component within the 610 Series Silverline family, engineered specifically for high-purity gas applications where contamination control and precise pressure regulation are paramount. This single-stage regulator features a robust nickel-plated brass bar stock body, offering excellent durability and resistance to environmental factors while maintaining a high degree of cleanliness suitable for non-corrosive specialty gases.

At the core of this regulator's performance is its stainless steel diaphragm. Unlike elastomeric diaphragms, the stainless steel construction prevents off-gassing and absorption, ensuring that the purity of the gas stream remains uncompromised from inlet to outlet. The assembly utilizes a metal-to-metal seal between the body and the diaphragm, eliminating the need for gaskets that could potentially leak or degrade over time. A 316 stainless steel filter is integrated into the inlet to trap particulates, further protecting the seat and the downstream system.

The unit is configured with 1/4" FNPT inlet and outlet ports, providing maximum versatility for integration into gas manifolds, custom piping systems, or laboratory setups where specific CGA connections are not required on the regulator body itself. It supports a maximum inlet pressure of 3500 PSI and provides a delivery pressure range of 0-500 PSI. For safety and system integration, the bonnet includes a 1/16" FNPT capturable vent port, allowing hazardous gases to be piped away in the event of a diaphragm failure. The design also facilitates panel mounting via a threaded bonnet or rear body taps.
