Electric butterfly valve option parameters

Electric butterfly valve option parameters

Electric butterfly valve is suitable for situations requiring flow regulation. Due to the butterfly valve in the pipeline pressure loss is relatively large, about three times of the gate valve, so in the selection of butterfly valve, the pipeline system should be fully considered by the pressure loss of the impact of the butterfly valve, should also consider the closing butterfly plate under the pressure of the pipeline media robustness. In addition, consideration must be given to operating temperature limits for resilient seat materials at elevated temperatures. Electric butterfly valve butterfly valve structure length and overall height is small, open and close fast, and has good fluid control characteristics, butterfly valve structure principle is suitable for making large-caliber valves. When butterfly valve is required to control flow, it is important to correctly select the size and type of butterfly valve so that it can work properly and effectively.

Electric butterfly valve features

Electric butterfly valve is one of the valve varieties commonly used in industrial pipeline. Butterfly valve small size, less material, light weight, larger diameter relative to other valves more economical and affordable. Pneumatic actuator can be quickly opened and closed by rotating 90°, easy to operate. At the same time, the valve has good fluid control characteristics. Butterfly valve is in the fully open position, butterfly plate thickness is the resistance when the medium flows through the valve body, so the pressure drop generated by the valve is small, when the open degree is about 15° to 70° between, and can be sensitive flow control, so large diameter flow regulation, butterfly valve has a greater advantage. Not suitable for process media with high particle and temperature.
