IntroductionHikelok BS3 series bellows-sealed valves are available with 316L stainless steel construction—316L VAR for bodies with butt weld end connections. Working pressure is up to 500 psig (34.4 bar),working temperature is from -40℉ to 200℉ (-40℃ to 93℃). Isolate system fluids and achieve reliable, leak-tight performance with Hikelok BS3 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.
