Lug type butterfly valve (threaded holes), type 1140

This butterfly valve is a lug type valve with threaded holes and can be used for many applications. The valve can be used as a stopper, a tap for discharging at the end of the pipeline, open/close and flow control. The threaded holes make it easy to install or uninstall from the pipeline. Operation can be manual, pneumatic, hydraulic or electric.
