Where Electric Butterfly Valves Are Applicable

1. Application advantages of electric butterfly valve


Electric butterfly valve has small structure height and overall height, fast opening and closing speed, and good fluid control characteristics. It is suitable for manufacturing large diameter valves. Correctly choose the size and type of the electric butterfly valve so that it can work normally and effectively. Generally, in throttling, regulating and controlling in mud medium, the structure length is required to be short, and the opening and closing speed should be fast.


2. The occasions where the electric butterfly valve is applicable


Electric butterfly valve is suitable for flow adjustment. Because the pressure loss of the electric butterfly valve in the pipeline is relatively large, it is about three times that of the gate valve. Therefore, when selecting an electric butterfly valve, the pressure loss of the pipeline system should be fully considered, and the strength of the pipeline medium pressure should be considered when the butterfly plate is closed. In addition, it is necessary to consider the limitation of the working temperature that the elastic valve seat material can withstand at high temperatures.


In the case of two-position adjustment, narrow passage, low noise, cavitation and vaporization, a small amount of leakage to the atmosphere and grinding media, electric butterfly valves can be used.


When the electric butterfly valve is used under throttling adjustment, strict sealing requirements, severe wear, low temperature and other special conditions, triple eccentric or double eccentric special design, as well as special designed metal seals with adjustment devices are required. The center line electric butterfly valve is suitable for fresh water, sewage, sea water, salt water, steam, natural gas, food, medicine, petroleum and various occasions that require complete sealing.
