<P>PROBLEM TO BE SOLVED: To provide an electric valve actuator which allows easy execution of a setting value modification operation without needing a special connector and its storage mechanism. <P>SOLUTION: This actuator includes: a first operation selector switch 21 which can execute mode selection operation between a direct manipulation mode, a remote manipulation mode, and a mode for the others; a second operation selector switch 22 which can execute mode selection operation between an open operation mode, a closure mode, and a stop mode; and a display part 23. The setting value modification operation, in which the second operation selector switch 22 modifies setting values of the operating conditions of a valve, becomes executable, and the setting values of the operating conditions at the time are displayed on the display part 23 by executing an input operation other than the mode selection operation on the second operation selector switch 22 when the first operation selector switch 21 is in the mode for the others. <P>COPYRIGHT: (C)2013,JPO&INPIT |
