252-8209 - Miller Smith Silverline 250 Series High Purity Liquid Cylinder Regulator CGA 580

High Purity Analytical Liquid Cylinder Regulator

The Miller Smith 252-82-09 Silverline High Purity Analytical Liquid Cylinder Regulator is a precision-engineered instrument designed to meet the rigorous demands of analytical laboratories and high-purity gas distribution systems. Part of the esteemed Silverline 250 Series, this single-stage regulator is specifically configured for use with liquid cylinders, featuring a rear-entry back mount design that simplifies connection geometry and reduces strain on piping and fittings. The unit is calibrated for a delivery range of 0-100 PSI, making it ideal for applications requiring stable, low-to-medium pressure control.

Constructed from rugged brass bar stock, the entire body, bonnet, and gauge casings are nickel-plated. This plating serves a dual purpose: it provides an aesthetic, professional finish suitable for laboratory environments, and more importantly, it offers superior protection against corrosion and environmental wear. At the heart of the regulator lies a large 1-7/8 inch stainless steel diaphragm. Unlike elastomeric diaphragms, stainless steel provides exceptional sensitivity to pressure changes and maintains its integrity even in cryogenic applications where temperature fluctuations can be a factor. This ensures a consistent flow rate and pressure delivery, critical for analytical instrumentation.

A key innovation in this model is Smith's exclusive Sure-Seat™ filtered seat technology. This design incorporates a filtration system directly into the seating area, preventing microscopic particles and contamination from compromising the seal. This feature significantly reduces maintenance downtime and repair costs, extending the operational lifespan of the unit. The regulator is equipped with large 2-1/2 inch single-scale gauges, allowing operators to easily monitor cylinder and delivery pressure from a distance. With a maximum inlet pressure rating of 3500 PSI and a CGA 580 connection, this regulator is compatible with a wide range of inert and high-purity gases.

Safety is paramount in high-pressure gas handling. The 252-82-09 includes a built-in capturable preset safety relief valve, providing an essential layer of protection against over-pressurization. Whether utilized for bulk gas distribution or precise laboratory work, this Miller Smith regulator delivers the reliability and purity required for critical industrial and scientific processes.
