What is Lug Butterfly Valve ?

Lug Butterfly Valve is a valve used for flow regulation in large pipe diameters in which the disc takes the form of disk. Operation is similar to that of a ball valve. A plate or disc is positioned in the center of the pipe. The disc has a rod passing through it that is connected to an actuator on the outside of the valve. Rotating the actuator turns the disc either parallel or perpendicular to the flow. Unlike a ball valve, the disc is always present within the flow, therefore a pressure drop is always induced in the flow, regardless of valve position.

Lug Butterfly Valve is usually used where the valve is at the end of a pipe since there will be no 2nd flange to secure the studs. Instead, lugs are cast on the valve with tapped holes which matches the bolt pattern for the size and pressure classification of the flange. Bolts are passed through the flange holes and are threaded into tapped holes of the lug.
