Butterfly valve

Butterfly valve, also known as flap valve, is a simple control valve, which can be used for the on-off control of low-pressure pipeline medium. It refers to a valve whose closing piece (disc or butterfly plate) is a disc and rotates around the valve shaft to open and close.
The valve can be used to control the flow of air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. It is mainly used to cut off and throttle the pipeline. The opening and closing part of butterfly valve is a disc-shaped butterfly plate, which rotates around its own axis in the valve body, so as to achieve the purpose of opening and closing or adjustment.
