Product Advantages 

Innovative Design Offering Robust Installation and Maintenance

The lug-type configuration supports independent flange fastening, granting installation flexibility and easy valve replacement without pipeline 

disruption. This design suits systems requiring precise flange alignments under DIN standards. Incorporating worm gear actuation delivers 

smooth, consistent 90-degree movement while minimizing operator effort. The compact, lightweight structure enhances responsiveness and 

space efficiency. With multiple certified materials and compliance to international standards, this butterfly valve embodies durable construction 

and modular adaptability, distinguishing it among butterfly valve suppliers focused on quality and operational excellence.

Enhanced Usability with Energy Efficiency and Leak Prevention

End users benefit from the low operating torque resulting in reduced energy consumption during valve actuation. The bi-directional tightness 

ensures leak-free performance vital for hazardous or sensitive media, boosting process safety. Ergonomic worm gear operation facilitates 

precise flow modulation, making handling accessible even in challenging environments. Its compatibility with a wide media spectrum, including 

acids and alkalis, expands user applications. Thanks to innovative sealing components and rigorous design validation, this butterfly valve offers 

an extended service life while ensuring consistent performance, raising user confidence in every control operation.

Use Scenarios 

Integrating Lug-Type Butterfly Valves in Municipal Water Systems

In municipal water treatment plants, precise isolation and flow regulation under demanding environmental conditions are crucial. The lug-type 

DIN standard butterfly valve performs a critical role by isolating pipeline sections for maintenance without dismantling the entire system. Its 

bi-directional sealing ensures no leaks, preserving water quality and system integrity. The worm gear actuation reduces operating torque, enabling 

smoother valve operations despite frequent cycling in high-capacity water networks. Compatibility with DIN and EN flange standards facilitates 

retrofit installations and workflow continuity, making it a preferred product among butterfly valve suppliers serving water utilities.

Ensuring Reliable Flow Control in Chemical Processing Facilities

Chemical industries require valves capable of withstanding corrosive media and varying pressure regimes. This standard butterfly valve adapted 

with materials like stainless steel and Viton seats provides chemical resistance necessary for acids, oils, and alkalis. The compact design and 

worm gear mechanism allow precise flow control critical in reaction vessels or pipeline sections. Compliance with international standards ensures 

consistent performance amid regulatory inspections. Integration into existing DIN-compliant piping systems occurs smoothly, supporting system 

validation and operational safety. This valve assists operators in maintaining strict process parameters while simplifying maintenance schedules 

through its lug-type design.
