An electrical drive apparatus for valves includes: a main body having an internal first receiving space in which a transmission unit is received; a drive unit disposed on one side of the main body for driving the transmission unit to rotate; a hand wheel fixed with a top section of the transmission unit, a lower section of the hand wheel being formed with several sockets; and a switch unit for controlling whether the hand wheel and the first transmission shaft can be rotated so as to switch the electrical drive apparatus between an electrical drive operation mode and a manual drive operation mode.
