221-0309 - Miller Smith Silverline 220 Series High Purity Two-Stage Regulator, CGA 580

Precision Control for Analytical Applications

The Miller Smith 221-03-09 Silverline High Purity Analytical Two-Stage Regulator is engineered to meet the rigorous demands of laboratory and analytical environments. Part of the esteemed 220 Silverline Series, this regulator is specifically designed for high purity, non-corrosive pure gases and mixtures. It is the ideal solution for controlling carrier gases or calibration mixtures used in sensitive equipment such as gas chromatographs, thermal conductivity detectors, and flame ionization detectors.

Advanced Two-Stage Design

One of the standout features of the 221-03-09 is its two-stage design. Unlike single-stage regulators that allow delivery pressure to rise as the cylinder pressure decays, this two-stage mechanism maintains a constant delivery pressure from a full cylinder down to nearly empty. This stability is critical in analytical applications where pressure fluctuations can compromise data integrity and equipment performance.

Superior Materials and Construction

Durability and purity are at the core of the Silverline series. The regulator features a stainless steel diaphragm which provides precise control over pressure and prevents contamination of the gas stream. The seat is filtered to further enhance gas purity and extend the service life of the unit by preventing debris from entering the seating area. The body, bonnet, and gauges are plated to offer superior protection against environmental factors, ensuring the regulator maintains its appearance and functionality over time.

Safety and Usability

Safety is paramount in high-pressure gas handling. This model includes a built-in capturable preset safety relief valve that protects the regulator components from over-pressurization. The unit is also capable of withstanding vacuums generated during purging operations, adding to its versatility. Operators will appreciate the large, 2-1/2 inch single scale gauges that make monitoring cylinder and delivery pressure effortless. With a delivery range of 0-60 PSIG and a CGA 580 inlet, it is perfectly suited for inert gas service.
