Claims

[Scope of utility model registration request]

means for adjusting the pressure of the self-regulating valve by moving it; means for driving the adjusting means to move; detecting means for detecting the position of the adjusting means and generating a position detection signal; a setting section that generates a set pressure signal in response to an operation of an operator; a control means that receives the position detection signal and the set pressure signal and controls the drive means so that the difference between the two becomes approximately 0; A pressure regulating device for a self-regulating valve, comprising means for measuring and displaying the pressure of the self-regulating valve, and a scale indicating an allowable movement range is provided on the setting section.
