If a butterfly valve is required to be used as a flow control, the main thing is to choose the correct size and type of valve. The structural principle of butterfly valves is particularly suitable for making large-diameter valves. Butterfly valves are not only widely used in general industries such as petroleum, gas, chemical industry, water treatment, etc., but also used in the cooling water system of thermal power stations.

There are two commonly used butterfly valves: clamp butterfly valve and flanged butterfly valve. The clamp butterfly valve is to connect the valve between the two pipeline flanges with stud bolts, and the flanged butterfly valve is to have a flange on the valve, and the flanges at both ends of the valve are connected to the pipeline flange with bolts.
