611-00080000 - Miller Smith Silverline 610 High Purity Oxygen Regulator CGA 540

Precision Control for High Purity Applications

The Miller Smith 611-00-08-00-00 Silverline High Purity Brass Single Stage Regulator is an elite instrument engineered for the rigorous demands of analytical laboratories and specialty gas delivery systems. Part of the renowned 610 Series, this regulator is specifically designed to maintain the integrity of high-purity, non-corrosive gases such as Oxygen. Unlike standard industrial regulators that utilize elastomeric diaphragms, the Silverline 610 features a robust stainless steel diaphragm. This critical design choice eliminates the risk of off-gassing and absorption associated with rubber components, ensuring that the gas stream remains uncontaminated from the cylinder to the point of use.

Constructed from nickel-plated brass bar stock, the body of the regulator offers exceptional durability and resistance to environmental corrosion while maintaining a clean, professional aesthetic suitable for laboratory environments. The internal architecture prioritizes purity with a metal-to-metal seal between the body and the diaphragm, removing the need for internal O-rings that could degrade over time or introduce impurities. A 316 stainless steel filter is integrated into the inlet to trap particulates, protecting the seat and extending the service life of the unit.

Operational safety and versatility are paramount in the 611-00-08-00-00 design. It supports a maximum inlet pressure of 3500 PSI, making it compatible with a wide range of high-pressure cylinders. The delivery pressure is accurately controlled within a 0-50 PSI range, monitored via a clear 2-1/2 inch single scale gauge. For installations requiring venting of potential leaks, the bonnet includes a 1/16 inch FNPT port, allowing hazardous gases to be piped away safely in the event of a diaphragm failure. Furthermore, the unit is ready for panel mounting with a threaded bonnet and rear-tapped body, offering flexible integration into gas management panels and benches.
