Lug Type Butterfly Valve

A lug type butterfly valve is a highly compact, quarter-turn rotary valve engineered with threaded metal inserts (lugs) around its body perimeter to deliver space-saving isolation and throttling in tight pipeline arrays. These threaded lugs allow the valve to be securely bolted directly between two pipe flanges, enabling the downstream piping to be fully disconnected for maintenance without disrupting upstream pressure or flow—a capability known as dead-end service. Operating via a flat disc that pivots on a central shaft, the valve offers a lightweight design with low flow resistance, though it requires precise flange alignment during installation to eliminate external leak paths. Piping layout contractors and commercial HVAC engineers can streamline inline maintenance and optimize limited workspace by importing certified lug type butterfly valves directly from leading manufacturers in China via our advanced B2B commercial platform.
