butterfly valve series

butterfly valve, also known as flap valve, is a simple structure of the control valve, but also can be used for low pressure pipe medium switch control. Butterfly valve refers to the closure (disc or butterfly plate) for the disc, around the valve axis rotation to achieve the opening and closing of a valve, in the pipeline mainly from the cut-off and throttling effect. Butterfly valve opening and closing parts is a disc-shaped butterfly plate, in the valve body around its own axis of rotation, so as to achieve the purpose of opening and closing or regulation. Butterfly valve is suitable for producing furnaces, gas, natural gas, liquefied petroleum gas, city gas, hot and cold air, chemical smelting and power generation and environmental protection engineering systems to transport a variety of corrosive, non-corrosive fluid media on the pipeline, used to regulate and cut off the flow of media.
