The electric butterfly valve is a valve with an electric actuator installed on the butterfly valve, and the valve switch is controlled by electricity.

ASIAV Electric Butterfly Valves Series

With the development of electric valves, many well-known valve enterprises at home and abroad produce electric valves. Electric butterfly valves are important executive units in the field of industrial automation control. It belongs to a variety of electric valves and electric control valves. It is widely used in textile, power station, petrochemical, heating and refrigeration, pharmaceutical, shipbuilding, metallurgy, light industry, environmental protection and other fields. This product can be used as cut-off valve, control valve and check valve of pipeline system. Complete manual control device, electric or pneumatic transmission device, which can meet the specific conditions of different working conditions. It meets the most stringent quality requirements and can be used for a very long time. Especially in the metallurgical steel and shipbuilding industries, it has a very high reputation.

The electric butterfly valve is suitable for the occasions requiring flow regulation. As the pressure loss of butterfly valve in the pipeline is relatively large, which is about three times that of gate valve, the influence of pressure loss on the pipeline system shall be fully considered when selecting butterfly valve, and the firmness of the butterfly plate under the pressure of pipeline medium during closing shall also be considered. In addition, the working temperature limit of the elastic seat material at high temperature must be considered. The structural length and overall height of the butterfly valve are small, the opening and closing speed is fast, and the butterfly valve has good fluid control characteristics. The structural principle of the butterfly valve is most suitable for making large-diameter valves. When the butterfly valve is required to be used for flow control, the most important thing is to correctly select the size and type of the butterfly valve so that it can work properly and effectively. In general, in throttling, regulating control and mud medium, the center line butterfly valve requires short structure length and fast opening and closing speed (1 / 4 turn). Low pressure stop valve (small pressure difference), butterfly valve is recommended. Butterfly valve can be selected for double position adjustment, constricted ground passage, low noise, cavitation and gasification, small amount of leakage to the atmosphere and abrasive medium. When throttling adjustment is required under special working conditions, or butterfly valves are used under working conditions such as strict sealing, severe wear and low temperature (cryogenic), special three eccentric or double eccentric butterfly valves with specially designed metal seal and regulating device shall be used.
