BS1-Bellows-Sealed Valves

IntroductionHikelok 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.
