PROBLEM TO BE SOLVED: To provide a solenoid proportional selector valve capable of easily providing an output flow rate favourable in linearity against an input signal even without referring to a flow rate characteristic view each time. SOLUTION: A controller provides a symmetrical broken line G concerning a broken line E approximate to a measured curve to express a relation of an input electric current and an output electric current and an ideal straight line F. Thereafter, the controller reads an ordinate Yn of a point R on the broken line G corresponding to an abscissa Xn of the input electric current and outputs it to a proportional electromagnet as the output electric current Yn. Consequently, it is possible to easily provide linearity of an input signal and an output signal without referring to a characteristic view each time.
