Description
Model 3420 Series - Single Stage Purity Brass In-Line Regulator
The Model 3420 Series regulators have been designed for line service to provide a means of dropping the pressure of house gas systems to a lower working pressure. The matched low inlet pressure and control valve design ensure stable pressure and flow from house systems. These regulators provide high purity control for laboratory use.
The Model 3420 Series regulators are recommended for use in applications where a house gas or distribution system pressure needs to be reduced to a lower working pressure. Typically these applications include use of the regulators for station pressure controls, carrier gas controls, blanketing operations and other high purity critical laboratory situations. The Model 3420 Series is compatible with gases that are non-corrosive in nature and gases that are compatible with the materials in the process stream.
Features
- Brass Barstock construction
