BS1-Bellows-Sealed Valves

Introduction Hikelok BS1 series bellows-sealed valves are available in a variety of models for system versatility.Working pressure is up to 1000 psig (68.9 bar),working temperature is from -20℉ to 900℉ (-28℃ to 482℃). Isolate system fluids and achieve reliable, leak-tight performance with Hikelok BS1 series bellows-sealed valves which use a packless design and a gasketed or welded seal. They are ideal for applications where the seal to atmosphere is critical, and we offer multiple options for general and high-purity service.
FeaturesMaximum working pressure up to 1000 psig (68.9 bar) Working temperature from -20℉ to 900℉ (-28℃ to 482℃ ) Flow coefficients (Cv) from 0.12 to 1.2 Variety of end connections 316 S.S., brass and monel 400 materials Panel and bottom mounting Bar, round handle are available Precion-formed metal bellows providers reliable seal Nonrotating stem tip: spherical, conical and regulating Gasket body to bellows seal is standard, weld seal also available Replaceable bellows and stem assembly Every valve is tested with helium for 10s to a maximum leak rate of 4 ×10-9 std cm3/s
