Product Description

 Electric butterfly valves are suitable for situations that require flow regulation. Due to the significant pressure loss of butterfly valves in the pipeline, which is about three times that of gate valves, when selecting butterfly valves, full consideration should be given to the impact of pressure loss on the pipeline system and the robustness of the butterfly plate to withstand the pressure of the pipeline medium when closed. 

In addition, it is also necessary to consider the limitations of the working temperature that elastic seat materials can withstand at high temperatures. The structural length and overall height of butterfly valves are small, with fast opening and closing speeds, and good fluid control characteristics.

The structural principle of butterfly valves is most suitable for making large-diameter valves. When it is required to use butterfly valves for flow control, the most important thing is to correctly select the size and type of butterfly valves, so that they can work properly and effectively. The centerline butterfly valve usually requires a short structural length and fast opening and closing speed (1/4 turn) in throttling, regulating control, and mud media.

 Low pressure cutoff (low pressure difference), butterfly valve is recommended. Butterfly valves can be used for dual position regulation, necked channels, low noise, cavitation and gasification phenomena, small leakage into the atmosphere, and abrasive media. 

When using butterfly valves under special operating conditions such as throttling adjustment, strict sealing requirements, severe wear, low temperature (deep cold), etc., special designed metal sealing belt adjustment devices with three or two eccentric special butterfly valves are required.
