Claims

[Scope of utility model registration request]

A valve mechanism having a movable spring receiver for adjusting valve opening pressure that is pressed against one end of the spring so as to adjust the bias state of a spring that presses the valve body against the valve seat, and adjusting the position of the movable spring receiver. a sensor for outputting a position voltage indicating the position of the movable spring receiver; and a sensor for driving the positioning solenoid by comparing the position voltage inputted as a feedback signal with a valve opening pressure setting signal. 9 control units for setting the valve opening pressure of the valve mechanism to a desired valve opening pressure in accordance with the valve opening pressure setting signal; A proportional control valve device characterized in that the shape of a required region of a characteristic curve is set so as to correspond to the shape of a position voltage characteristic curve with respect to a detection position of the sensor corresponding to the required region.
