Mastering more knowledge of electric butterfly valves will better enable products to be used in major projects, better electric butterfly valves will be better recognized by market consumers, and the packing process of electric butterfly valves will be better handed over to customers to bring better benefits to customers!

Metal sealed valves generally have longer service life than elastic sealed valves, but it is difficult to achieve complete sealing. Metal seals can get used to higher working temperatures, while elastic seals have the disadvantage of being constrained by temperature. If the butterfly valve is required to be used as flow control, the first thing is to correctly select the size and type of the valve. The structure principle of butterfly valve is particularly suitable for manufacturing large diameter valves. Butterfly valves are not only widely used in petroleum, gas, chemical, water treatment and other general industries, but also used in the cooling water system of thermal power plants. The commonly used butterfly valves are wafer type butterfly valve and flange type butterfly valve. Wafer type butterfly valve uses stud bolts to connect the valve between two pipe flanges. Flange type butterfly valve has flanges on the valve, and bolts are used to connect the two flanges on the valve to the pipe flanges.
