What Is The Difference Between Electric Ball Valve And Electric Butterfly Valve?

Electric ball valve and electric butterfly valve are the more commonly used valves. They are universal in some occasions, and they can only be used one of them in some conditions. The difference between the two lies mainly in the structure and switching principle. The electric ball valve is the evolution of the plug valve, and the opening and closing part is a sphere. The opening and closing parts of the electric butterfly valve are disc type left and right open.

The butterfly valve is slightly less tight than the ball valve, but in the large-diameter valve, the butterfly valve has unique advantages over the ball valve; when adjusting the flow rate, the butterfly valve does not have a large adjustment range, and the V-shaped ball valve regulates accurately. In addition, ball valves have advantages over butterfly valves in high pressure piping.
