What are the structural characteristics of the electric butterfly valve? The butterfly plate of the electric butterfly valve shall be installed in the diameter direction of the pipeline. In the cylindrical channel of the butterfly valve body, the disc shaped butterfly plate rotates around the axis, and the rotation point of view is between 0 ° - 90 °. When the valve rotates to 90 °, the valve is fully open. The butterfly valve is simple in structure, small in size and light in weight, and only consists of a few parts. The valve can be quickly opened and closed only by rotating 90 °. The operation is simple. Together, the valve has outstanding fluid control characteristics. When the butterfly valve is in the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body, so the pressure drop generated by the valve is very small, so it has good flow control characteristics.

Check whether there are foreign matters inside the valve. If there are foreign matters, the opening and closing ports of the valve will be stuck. The valve can be started normally only after the foreign matters are removed. When cleaning, be careful and quickly remove all foreign matters. More "spa" pneumatic on-off ball valves are provided. The advantage of pneumatic on-off ball valves over other valves is that the sealing of pneumatic ball valves is strong. The key is to do a good job in the maintenance of pneumatic butterfly valves for long-term storage. What are the main tasks to be done in the installation and assembly of electric ball valves
