装置。 When the electric valve open and close switch is turned on, the electric valve open and close excitation coils are energized. A drive motor is interposed in the line connecting the two so that it can freely rotate in forward and reverse directions, and each self-holding circuit of the excitation coil for opening and closing the electric valve is disconnected from the power supply when the electric valve is in the fully open position and the fully closed position. In an electric valve drive device that is equipped with a limit switch that opens and closes the electric valve, the self-holding circuit starts operating when the electric valve open and close switch is turned on, and a limit switch is installed in the piping in which the electric valve is installed. A non-contact output timer is used as an interlock mechanism, which has a set time that is longer than the time required for the contacts to close instantaneously due to the impact of a water hammer, etc., and shorter than the operating time of the electric valve opening and closing switch. An electric valve drive device characterized by:
