Claims

[Scope of Claim for Utility Model Registration] (1) An electric motor that opens and closes the valve of a valve unit, a motor circuit section that includes an external connection terminal that is connected to the electric motor via a lead wire, and a motor circuit section that is connected to the motor circuit section. an operation control section that controls the rotation of the electric motor of the motor circuit section, which includes an opening/closing limit switch section that regulates the opening/closing operation of the valve of the valve unit; and an external connection terminal connected to the opening/closing limit section;
In an electric operating device including a power supply circuit section that supplies power to the electric motor via the operation control section, a circuit loop between the motor circuit section and the operation control section is changed between the motor circuit section and the operation control section. An electric operating device for a valve, characterized in that it is configured by providing a switching circuit section for switching. (2) The switching circuit section is configured by a manual switching switch having a plurality of contacts connected between the power supply lead wire of the motor circuit section and the open/close limit switch section of the operation control section. An electric operating device for a valve according to claim 1 of the utility model registration claim.
