Product Advantages


Robust Design Ensuring Secure, Modular Installation

The valve’s lug-type stainless steel body enables simple bolt-up between flanges, allowing independent removal or 

maintenance without dismantling entire piping sections. Its compact wafer-style form combined with the enhanced 

lug design offers structural flexibility for confined spaces and robust flange connections. Utilizing PTFE seats and 

multiple material options assures corrosion resistance and chemical compatibility across industry requirements. 

This modular design aligns with modern piping systems, delivering adaptable, secure installation benefits that merge 

the convenience of wafer butterfly valves with the strength of lug-style flanges, supporting both new builds and retrofit 

projects.


Exceptional User Experience and Operational Efficiency

Thanks to its minimized operating torque and precise PTFE sealing, the valve operates effortlessly for quick open-close 

cycles, reducing operator fatigue and maintenance intervals. Its lightweight construction eases handling on-site during 

installation or replacement. The bi-directional tightness eliminates leakage concerns in either flow direction, improving 

process control accuracy and safety. Users experience durable, bubble-tight sealing over thousands of cycles that lowers 

life-cycle costs. With flexible seat and O-ring materials, this product caters to diverse media with reliability, making it an 

invaluable valve for those seeking hassle-free, high-performance flow control solutions.



Use Scenarios


Optimizing Flow Control in Chemical Processing Plants

In chemical manufacturing environments, where aggressive acids and alkalis commonly flow through pipelines, the Lug 

Stainless Butterfly Valve plays a vital role in ensuring tight sealing and corrosion resistance. Its PTFE lining withstands 

harsh chemical exposure, preventing leakage and material degradation. The valve’s lug design simplifies installation and 

periodic maintenance amid complex piping networks, supporting production uptime. Operators rely on its low actuation 

torque and precise bi-directional closure for safety-critical shutdowns and flow regulation. Integration with standard flange 

connections streamlines system upgrades, making it a key component in stringent chemical processing workflows requiring 

durability and safety compliance.


Enhancing Reliability in Municipal Water and Wastewater Systems

For municipal water treatment and sewage management, this valve supports efficient pipeline isolation and flow throttling tasks. 

The stainless steel body ensures long service life in outdoor and variable environments, while PTFE seats provide resistance 

against chemical additives commonly used for water treatment. Its lug-type flange connection offers secure bolted installation 

crucial for frequent maintenance cycles and section isolations. The quick 90-degree operation speeds up manual control, 

saving operator effort during routine and emergency interventions. This butterfly valve’s compatibility with multiple media, 

including water, steam, and air, positions it as a versatile asset integrated seamlessly into municipal infrastructure to maximize 

performance and reduce operational downtime.
