    Classification and differences of electric disc ball valves:

    The electric one-piece ball valve is one-piece, and the ball is fixed by a plug, which facilitates its maintenance and can be used in working conditions that require quick opening and closing.

    The electric two-piece ball valve is composed of two parts. The ball is clamped and fixed by the two valve bodies. Maintenance is relatively complicated. The tightness of the middle screw is related to whether there will be air leakage. 

    The electric three-piece ball valve is similar to the two-piece ball valve. It is composed of left and right end covers and a middle valve body, and is clamped by neck flanges on both sides. Its pressure is higher than the other two types.
