Lug Butterfly Valve — Product Description

This lug butterfly valve combines a rubber-sealed body with a carbon steel or stainless steel valve plate and stem, purpose-built for demanding industrial environments. It is suitable for temperatures up to 80–120°C and is widely used across food processing, pharmaceutical, chemical, petroleum, power generation, textile, and papermaking industries — as well as modern data center chilled water systems and AI server cooling circuits — for precise flow regulation and medium shutoff in water supply, drainage, and gas pipelines.

Key Features:

Innovative, compact design with a lightweight structure for rapid opening and closing.
Low operating torque — smooth, effortless control even in high-cycle data center cooling valve applications.
Flexible installation in any orientation, with minimal maintenance requirements.
Replaceable seals with reliable bi-directional zero-leakage sealing performance.
Sealing materials offer excellent aging resistance and corrosion resistance, ensuring long service life — ideal for the continuous-duty demands of data center chilled water valves and AI server cooling infrastructure.
