AWWA butterfly valve, also known as flap valve, is a simple structure of the regulating valve, can be used for low-pressure pipeline media switching control of the butterfly valve refers to the closing member (valve flap or butterfly plate) for the disc, rotating around the valve axis to achieve the opening and closing of a kind of valve. AWWA butterfly valve can be used to control the flow of various types of fluids, such as air, water, steam, a variety of corrosive mediums, slurries, oils, liquid metals and radioactive media. Mainly in the pipeline to cut off and throttling effect.AWWA butterfly valve opening and closing member is a disc-shaped butterfly plate, rotating around its own axis in the valve body, so as to achieve the purpose of opening and closing or regulating.AWWA butterfly valve is not only in the petroleum, gas, chemical industry, water treatment, and other general industry has been widely used, but also used in thermal power plants in the cooling water system.
