Swagelok SS-6BG-MM stainless steel bellows sealed valve is designed to isolate system fluids and achieve reliable, leak-tight performance. Featuring a straight pattern and manual actuation, this valve uses a packless design and a welded seal. Bellows valves are ideal for applications where the seal to atmosphere is critical, and multiple options are available for general and high-purity service.
