Abstract: A cooling water control valve apparatus capable of independently controlling flow rates of cooling water in two lines with a single apparatus for cooling water control and capable of achieving cost reduction. A cooling water control valve apparatus which adjusts a flow rate of cooling water for cooling an object to be cooled includes two inlet ports through which cooling water is introduced, an electrical control valve which is arranged at a first passage communicated with one of the inlet ports and which adjusts a flow rate of cooling water flowing through the first passage with electronic control, and a thermosensitive valve which is arranged at a second passage communicated with the other of inlet ports and which adjusts a flow rate of cooing water flowing through the second passage owing to displacement of a temperature detecting medium with temperature.
