252-2002 - Miller Smith 250 Series Silverline Liquid Cylinder Regulator, CGA 320, 0-100 PSI

Precision Control for High Purity Applications

The Miller Smith 252-20-02 Silverline High Purity Analytical Liquid Cylinder Regulator is engineered to meet the rigorous demands of laboratory and industrial gas distribution systems. Designed specifically for use with liquid cylinders (dewars), this regulator features a specialized rear-entry inlet that allows for seamless, direct mounting to the cylinder's gas use valve. This configuration eliminates the need for awkward piping adapters and ensures a secure, streamlined connection essential for maintaining the integrity of high-purity gas streams.

Advanced Materials for Cryogenic Service

Cryogenic applications present unique challenges, particularly regarding temperature stability and material compatibility. The 252-20-02 addresses these with a large 1-7/8 inch stainless steel diaphragm. Unlike elastomeric diaphragms that can stiffen or crack under low-temperature conditions often associated with gas withdrawal from liquid sources, stainless steel maintains its flexibility and responsiveness. This ensures precise pressure regulation and a consistent flow rate, which is critical for analytical instrumentation and process control. Furthermore, the entire body, bonnet, and gauge casings are nickel-plated, providing a robust shield against corrosion and tarnishing, thereby extending the unit's operational lifespan in challenging environments.

Exclusive Sure-Seat™ Technology

One of the standout features of the Smith Equipment Silverline series is the exclusive Sure-Seat™ filtered seat technology. Gas contamination is a leading cause of regulator failure; particles can lodge in the seating area, causing creep or leaks. The Sure-Seat design incorporates a filtration system that prevents microscopic contaminants from entering the critical seating area. This innovation not only reduces the frequency of repairs and maintenance but also minimizes costly downtime, ensuring your gas delivery system remains reliable day in and day out.

User-Friendly Design and Safety

Safety and ease of use are paramount in the design of the 252-20-02. The regulator is equipped with large, 2-1/2 inch single-scale gauges that are easy to read from a distance, allowing operators to monitor cylinder and delivery pressures at a glance. A built-in capturable preset safety relief valve adds an extra layer of protection by venting excess pressure safely away from the regulator body. With a delivery range of 0-100 PSI and a CGA 320 connection suitable for Carbon Dioxide (CO2), this regulator is the definitive choice for professionals requiring high-purity gas control.
