Plast-O-Matic PRD Pressure Regulator

Plast-o-matic® type PRD pressure differential regulators have a pressure differential to 50psi and are used for corrosive and high purity liquids. Their reinforced rolling diaphragm assures sensitive control. A typical application improves optimum filter efficiencies and safety by limiting the pressure differential across a filter or a combination of filters as used in the manufacture of ultra high purity water for the semiconductor industries.
