Product Overview
The NUPRO SS-BNV51-O is a high-purity, bellows-sealed valve engineered by NUPRO (a Swagelok brand) for critical process and pneumatic fluid control applications. Utilizing a welded metal bellows sealing mechanism, this valve isolates the process media from the actuator and atmosphere, eliminating stem leakage and ensuring zero fugitive emissions. The SS-BNV51-O is constructed from 316 stainless steel and is designed for precise on/off control of gases and liquids in analytical, research, and industrial process systems where containment integrity and repeatable performance are paramount. Its compact body and Swagelok tube fitting end connections allow direct integration into high-purity and corrosive service manifolds without the need for additional sealing interfaces.

Engineering Features & Advantages
- Hermetic Bellows Seal: The welded metal bellows provides a primary containment barrier that eliminates stem packing leakage, making the SS-BNV51-O ideal for toxic, corrosive, or expensive media where fugitive emissions are unacceptable.
- Precision Flow Control: The non-rotating stem tip and fine-thread actuation allow smooth, repeatable throttling and bubble-tight shutoff, ensuring accurate process regulation in analytical and dosing systems.
- Industrial Reliability: Constructed for continuous duty with durable, corrosion-resistant materials and proven engineering for maximum system uptime.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original NUPRO OEM standards, ensuring drop-in replacement without modification to existing manifolds or piping.
