The electric butterfly valve is a valve that uses a circular butterfly plate as a start and stop part and rotates with the valve stem to open, close and adjust the fluid channel. The butterfly valve is not only simple in structure, small in size, light in weight, low in material consumption, and small in installation size, but also has a small driving torque, is easy to operate and agile, and also has excellent flow regulation function and closing and sealing characteristics. In the field of large and medium calibers, medium and low pressure applications, the butterfly valve is the dominant valve form.
