254-8202 - Miller Smith 250 Series Silverline High Purity CO2 Regulator 0-200 PSI

Miller Smith 254-82-02 Silverline High Purity Analytical Liquid Cylinder Regulator

The Miller Smith 254-82-02 Silverline Regulator is a premium solution designed specifically for high-purity analytical applications involving liquid cylinders. Engineered by Miller Smith Equipment, this regulator is part of the renowned 250 Silverline Series, which is celebrated for its precision, durability, and contamination control. This specific model is configured with a CGA 320 inlet connection, making it the ideal choice for Carbon Dioxide (CO2) service in laboratories, research facilities, and bulk gas distribution systems.

One of the standout features of this regulator is its construction. The body, bonnet, and gauges are fully nickel-plated. This plating serves a dual purpose: it provides an aesthetically clean finish suitable for laboratory environments and, more importantly, offers superior protection against corrosion. This ensures that the regulator maintains its integrity and purity over a long service life, even in challenging environments. At the heart of the device lies a large 1-7/8 inch stainless steel diaphragm. Unlike rubber or neoprene diaphragms, stainless steel does not off-gas or absorb contaminants, ensuring that the gas stream remains pure. Furthermore, the stainless steel construction is essential for cryogenic applications, where extreme cold from liquid cylinder boil-off can damage lesser materials.

Operational efficiency is enhanced by the regulator's thoughtful design. It features a back-mount inlet connection, which is specifically engineered to attach seamlessly to liquid cylinders (dewars) without putting strain on the piping or the operator. The large 2-1/2 inch single-scale gauges are easy to read from a distance, allowing technicians to monitor cylinder contents and delivery pressure at a glance. The delivery pressure range of 0-200 PSIG provides versatile control for various analytical instruments and process applications.

Safety and reliability are paramount in the 254-82-02. It incorporates Miller Smith's exclusive Sure-Seat™ filtered seat technology. This innovation prevents microscopic particles and contamination from entering the high-pressure seating area, which is a common cause of regulator failure and creep. By filtering the gas stream before it reaches the seat, maintenance costs are reduced, and downtime is minimized. Additionally, a built-in capturable preset safety relief valve provides an extra layer of protection for downstream equipment.
