Hikelok BS2 series bellows-sealed valves enhance reliability, versatility, and safety—with a secondary containment system that prevents leaks to atmosphere even if the primary seal fails.Working pressure is up to 2500 psig (172 bar),working temperature is from -20℉ to 1200℉ (-28℃ to 649℃ ). Isolate system fluids and achieve reliable, leak-tight performance with Hikelok BS2 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.
