Swagelok SS-10BK-MM-1C is a straight-pattern stainless steel bellows sealed valve equipped with a normally closed pneumatic actuator. It uses a packless design and a welded seal to isolate system fluids and achieve reliable, leak-tight performance.

Bellows valves are ideal for applications where the seal to atmosphere is critical. This model offers a PCTFE stem tip, 10 mm Swagelok tube fittings on both connections, and undergoes special SC-11 cleaning and packaging for general and high-purity service.
