7. The electric switch butterfly valve is small in size, reliable in performance, simple in matching, especially light in weight, and powerful in circulation, which is most suitable for clean liquid and gas media. 　　　　

The power component of electric ball valve is mainly used to control the valve and is closely connected with the valve. This component is mainly driven by electricity. During operation, it is affected by the stroke, rotating moment and axial direction driving force. Because the special properties and utilization efficiency of the power component of the valve depend on the type of valve, the operation specification of the component and the position of the valve on the pipeline equipment, Because the customer needs to know and master the selection and assembly method of power parts, and then select the appropriate parts, the overload situation needs to be fully considered. Overload actually means that the torque force of work transfer is greater than the torque force of control. This inspection link is a very important part of the whole valve inspection.
