Swagelok SS-BNV51-DU-C Bellows Valve

SS-BNV51-DU-C is a Swagelok 316L stainless steel high-purity bellows-sealed valve with a 1/4 in. female Swagelok VCR fitting and a normally closed (NC) actuator. The bellows seal isolates the process fluid from the valve body to maintain clean, high-purity service in demanding environments. It is SC-01 cleaned with a standard surface finish (not EP), aligning with stringent cleanliness requirements for critical fluid handling. This model is part of Swagelok’s BN Series of high-purity bellows valves, delivering reliable shutoff and metal-seal performance in applications such as semiconductor, pharmaceutical, and biotech processes where leak-tight isolation and cleanability are essential.
