Lug type butterfly valve (through holes), type 1150

This butterfly valve is a lug type valve with through holes and can be used for many applications. The through holes makes it easy to install or uninstall the valve from the pipeline. 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.
