Product introduction
The BS1 series bellows sealed valves are available in a variety of models to achieve the versatility of the system. Operating pressures up to 1000 psig (68.9 bar) and operating temperatures from -20°F to 900°F (-28°C to 482°C). The Hikelok BS1 series bellows sealed valves feature a packless design and a gasketed or welded seal to isolate system fluids and provide reliable leak-proof performance. They are ideal for applications where atmospheric sealing is critical and we offer a wide range of options for general and high purity services.
