Model HP701EN-125-660 Regulator

Model 701EN is a single-stage regulator with an electroless nickel plated brass body for primary pressure control of corrosive and acid forming gases or gas mixtures. Harris strongly recommends the use of a 316 SS cross purge assembly for highly corrosive and acid forming gases. The use of a cross purge will eliminate moisture that will result in acid corrosion inside the regulator. Typical applications include hydrogen chloride, hydrogen bromide, hydrogen sulfide, boron trichloride, dichlorosilane and chlorine.
