。A valve element that opens and closes the primary flow path and the secondary flow path, a main diaphragm that operates the valve element and partitions the pressure regulating chamber from the flow path side, and a main diaphragm that presses the main diaphragm toward the flow path side and a pressure regulating spring whose pressing force is variable; an introduction hole for introducing pilot pressure into the pressure regulating chamber; a diaphragm disposed facing the upstream flow path; a lower pressure regulating spring that is displaced toward the valve body in response to pressure changes; a rond that operates in conjunction with the diaphragm and moves toward and away from the valve body to actuate the valve body to open and close the flow path; and the rond. 1. A pressure regulating valve, comprising: position adjusting means for adjusting the position of the valve body relative to the valve body.
