The electric control valve and the electric control valve ball valve can adjust the pressure and flow of the valve medium. Describe the characteristics, application and working principle of the two. First of all, the electric control valve is a straight stroke valve, and the electric control valve ball valve is an angle stroke valve. The difference is that the electric control valve adopts a low in and high out structure in the form of stop valve; the electric control valve ball valve adopts a V-type full bore structure, and the linearity of the electric control valve is better than that of the electric control valve, and the flow resistance of the electric control valve ball valve is lower than that of the electric control valve. The core difference between the two lies in the electric control The valve is used in the occasion of regulating valve. It is a professional regulating valve. The ball valve of regulating valve is a coarse regulating valve, but it can be cut off and adjusted at the same time. The electric regulating valve can only be used for regulating but not cut off at the same time.
