Diaphragm valves for Ultra-High purity applications
What are
Diaphragm valves.
Benefits of Flowlink
diaphragm valves.
Engineers design Flowlink valves to meet the most demanding ultra high purity requirements. As a manufacturer specialized in UHP fluid control solutions, we focus on performance, reliability, and long-term process stability.
Leak-tight design for UHP systems
FLOWLINK diaphragm valves feature a leak-tight design engineered to prevent leakage and contamination. Our experts made and tested each valve to ensure tight sealing. This makes them suitable for important UHP gas and chemical systems where safety and purity are key.
Minimal dead volume
Thanks to an optimized internal geometry, our valves minimize dead volume. This lowers particle generation, stops fluid stagnation, and boosts purge efficiency. These are important benefits for high-purity and high-cycle uses.
Excellent chemical compatibility
Our valves are compatible with a wide range of aggressive gases and chemicals. Carefully selected materials and great surface finishes ensure resistance to corrosion and chemical attack, even in harsh operating conditions.
Long service life
Designed for durability, our diaphragm valves offer a long service life with consistent performance over time. The robust diaphragm design reduces wear and maintenance requirements, helping lower total cost of ownership.
Up-to-date & customized documentation
Our experts provide complete and up-to-date technical documentation, including material certificates, test reports, and compliance information. Customized documentation packages are available to meet customer and project-specific requirements.
Technical
Specifications.
Flowlink’s valves are designed to meet strict UHP standards. They can also be adjusted for many operating conditions.
Materials
You can find high-grade stainless steel, like 316L with low surface roughness. All materials are fully traceable.
Helium leak rate
Each diaphragm valve is tested to meet strict helium leak rate standards. This ensures great sealing performance for ultra-high purity processes.
Temperature & pressure ratings
FLOWLINK valves are designed to operate across a wide temperature range, suitable for both ambient and elevated temperature applications commonly found in UHP systems.
Our diaphragm valves with manual actuator are rated for high-pressure operation, ensuring safe and reliable performance in demanding gas and chemical delivery applications.

FAQ about diaphragm valves.
Why are diaphragm valves ideal for UHP applications ?
They are ideal for UHP applications because the diaphragm isolates the process media from the valve mechanism. This design minimizes contamination, reduces particle generation, and provides excellent leak-tight performance, which is critical in ultra high purity environments.
How do diaphragm valves differ from bellows valves ?
Diaphragm valves use a diaphragm assembly to stop the flow of a fluid and create a seal. Bellows valves use a metal bellows assembly instead. They usually have less dead volume and are easier to maintain. Bellows valves are more common for higher temperature or higher pressure ratings.
