Lugged Butterfly Valve

A lugged butterfly valve is a highly versatile, quarter-turn rotary valve featuring a series of threaded metal inserts (or "lugs") positioned around the perimeter of its compact body. These threaded lugs allow the valve to be securely bolted directly between two opposing pipe flanges using two independent sets of bolts (one set for each flange). The premier engineering advantage of this lugged configuration is its ability to facilitate dead-end service or single-sided pipeline disassembly; operators can completely disconnect and service piping on one side of the valve while the opposite side remains fully pressurized and isolated. Piping layout designers and HVAC contractors can maximize system maintenance flexibility and minimize line shutdown times by importing certified lugged butterfly valves directly from leading manufacturers in China via our advanced B2B commercial platform.
