614-40080000 - Miller Smith 610 Series High Purity Oxygen Regulator 0-500 PSI CGA 540

Precision High Purity Regulation

The Miller Smith 614-40-08-00-00 Silverline High Purity Brass Single Stage Regulator is engineered for applications demanding stringent gas purity and precise pressure control. Part of the renowned 610 Series, this regulator is specifically designed to prevent contamination in high-purity systems, making it an essential component for analytical instrumentation, gas chromatography, and other laboratory environments where gas integrity is paramount.

At the core of this regulator is a specially designed stainless steel diaphragm. Unlike elastomeric diaphragms that can outgas or permeate, the stainless steel construction ensures a metal-to-metal seal with the body, providing a leak-tight barrier that maintains the purity of the gas stream. This design also offers exceptional sensitivity and stable regulation of delivery pressure, even as cylinder pressure decays. The regulator features a filtered seat for added protection against particulates, further ensuring the cleanliness of the gas delivery.

Constructed from brass nickel-plated bar stock, the body offers the durability of brass with the corrosion resistance and aesthetic finish of nickel plating. The unit is equipped with a 316 stainless steel filter and a 2-1/2 inch single scale gauge for clear pressure monitoring. For safety and versatility, the bonnet includes a 1/16 inch FNPT port to vent hazardous gases in the unlikely event of a diaphragm failure, and the threaded bonnet design facilitates easy panel mounting. With a delivery range of 0-500 PSI and a CGA 540 connection for oxygen service, this regulator represents a premium solution for non-corrosive specialty gas delivery.
