The Model BR back-pressure regulator (photo) is available for a wide range of gases and liquids. With the appropriate options, applications include upstream overpressure regulation of cryogenic liquids, sour gas, industrial gases and chemicals and common industrial fluids, such as water, oil, steam and compressed air. Available in globe or angular porting configurations, the Model BR valve controls inlet pressures up to 200 psig (13.8 barg), in multiple spring ranges, and can be utilized for the majority of industrial pressure-relief applications. The back-pressure regulator is available in five sizes, from 3/8 to 2 in., and can handle materials from 20 to 400°F, with the appropriate body/spring chamber and trim material combinations. — Cashco, Inc., Ellsworth, Kan.
