222-2009 - Miller Smith Silverline 220 Series High Purity Two-Stage Regulator, CGA 580, 0-100 PSI

Precision Control for Analytical Applications

The Miller Smith 222-20-09 Silverline High Purity Analytical Two Stage Regulator is engineered specifically for the rigorous demands of laboratory and analytical environments. When dealing with gas chromatography, thermal conductivity, or flame ionization detection, the stability of your carrier gas is paramount. This regulator features a sophisticated two-stage design that reduces cylinder pressure in two steps, ensuring that the delivery pressure remains rock-steady even as the cylinder pressure drops from full to empty. This eliminates the need for constant manual adjustments and ensures the integrity of your analytical baselines.

Uncompromised Purity

Contamination is the enemy of accurate analysis. The 222-20-09 is constructed with a stainless steel diaphragm, a critical feature that prevents the outgassing and absorption often associated with elastomeric diaphragms. This ensures that the gas stream remains as pure at the outlet as it was in the cylinder. Furthermore, the regulator includes a filtered seat that not only protects the internal mechanism from particulate damage but also adds an extra layer of filtration to the gas stream, extending the service life of the unit and maintaining high purity standards.

Robust and Reliable Construction

Despite its delicate precision, the Silverline series is built to last. The body and bonnet are machined from rugged brass bar stock and plated for superior protection against environmental corrosion. The regulator is capable of withstanding vacuums generated during purging operations, a common requirement in high-purity gas handling. With large, easy-to-read 2-1/2 inch gauges and a precise needle valve outlet, operators can monitor and control flow with exceptional accuracy. The unit is rated for a maximum inlet pressure of 3500 PSI and delivers a precise output range of 0-100 PSI, making it an ideal choice for a wide range of non-corrosive specialty gas mixtures.
