Product Overview
The SWAGELOK 6LV-BNC111-WH is a high-purity diaphragm valve engineered for critical process and pneumatic flow control applications where media containment, cleanliness, and leak integrity are paramount. Manufactured by Swagelok, a globally recognized authority in fluid system components, this valve utilizes a flexible diaphragm as the sole moving sealing element, isolating the actuation mechanism from the process media. This design eliminates packing, seats, and stem seals that can trap contaminants or degrade over time, making the 6LV-BNC111-WH ideally suited for semiconductor, pharmaceutical, and analytical instrumentation systems requiring ultra-clean service. The valve operates as a two-way, normally closed (NC) configuration, providing reliable shutoff and precise flow control in high-purity gas and liquid delivery lines.

Engineering Features & Advantages
- Precision Performance: The diaphragm sealing principle provides bubble-tight shutoff and excellent flow control characteristics, with minimal dead volume and no packing to leak or adjust.
- High-Purity Construction: Designed for ultra-clean service with minimal particle generation and low extractables, meeting stringent semiconductor and pharmaceutical cleanliness standards.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with a robust body and diaphragm assembly that withstands repeated cycling and thermal stress.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original OEM standards, ensuring drop-in replacement without system modification.
- Contamination-Free Operation: The isolation of the actuation mechanism from the process media prevents cross-contamination and extends service life in corrosive or high-purity environments.
Typical Industrial Applications
The SWAGELOK 6LV-BNC111-WH high-purity diaphragm valve is widely deployed in semiconductor fabrication for ultra-high-purity gas and chemical delivery, pharmaceutical and biotech processing for sterile fluid handling, analytical instrumentation for precise sample and reagent control, and aerospace ground support systems requiring leak-tight, contamination-free performance. Its robust design also suits research laboratories and industrial gas panels where media integrity and reliable shutoff are critical
