255-0009 - Miller Smith 250 Series Silverline High Purity Regulator, 0-350 PSI, CGA 580

Precision Control for High Purity Applications

The Miller Smith 255-00-09 Silverline High Purity Analytical Liquid Cylinder Regulator is engineered to meet the rigorous demands of laboratory and industrial gas handling. Designed specifically for use with liquid cylinders, this regulator features a rear-entry back mount configuration that simplifies installation and reduces strain on connections. With a delivery pressure range of 0-350 PSIG and a CGA 580 inlet, it is perfectly suited for inert gas applications requiring stable and precise flow control.

Advanced Contamination Protection

One of the standout features of the 250 Silverline series is the exclusive Sure-Seat™ filtered seat technology. This innovation prevents microscopic contamination from entering the seating area, a common cause of regulator failure and drift. By filtering the gas stream before it reaches the critical sealing surfaces, the Sure-Seat™ design significantly extends the service life of the regulator and reduces maintenance downtime. This is critical in high-purity analytical environments where gas integrity is paramount.

Durable Construction for Cryogenic Service

Cryogenic applications can be tough on equipment, but the Miller Smith 255-00-09 is built to last. The regulator body, bonnet, and gauges are fully nickel-plated, providing superior protection against corrosion and wear. Internally, a large 1-7/8" stainless steel diaphragm provides the sensitivity needed for precise pressure control while offering the durability required to withstand the temperature fluctuations associated with cryogenic gas withdrawal. The use of a stainless steel diaphragm also ensures that the regulator does not off-gas or contaminate the process stream, maintaining the high purity of your analytical gases.

User-Friendly Design

Operational efficiency is enhanced by the inclusion of large 2-1/2" single scale gauges. These high-visibility gauges make it easy for technicians to monitor cylinder and delivery pressures from a distance, improving safety and workflow in busy laboratories or gas distribution centers. Whether you are managing bulk gas distribution or running sensitive analytical instruments, the Miller Smith 255-00-09 delivers the reliability and precision you need.
