PROBLEM TO BE SOLVED: To perform initialization to the correction of a variation and the pressure of an output port by finely adjusting the position of a pressure control member in a regulator capable of setting two or more pressures digitally. SOLUTION: A parallel pin 41 engages with any engagement surface of the cam surface of the pressure control member 30 by operating a level handle 48. The deflection amount of a pressure control spring 31 is controlled. A force acting on a diaphragm 13 is controlled to stepwise control the pressure of the output port 15. A hollow setting screw 37 is screwed in a regulator main body 10. A cam shaft 39 engaged with the parallel pin 41 is relatively rotatably inserted into the hollow hole of the setting screw 37. The position of the pressure control member 30 is finely adjusted upward, downward by the rotation operation of the setting screw 37 to perform the correction of the pressure of the output port 15 and the initialization.
