Summary:PROBLEM TO BE SOLVED: To provide a pressure governor capable of preventing gas pressure supplied to a consumer from rising by changing the set values of secondary pressure in accordance with a time zone when gas quantity consumed becomes smaller when the difference of elevation exists between a spot where the pressure governor is installed and spots where the consumer lives to which gas is supplied. SOLUTION: This governor is provided with a motor operated valve V which is attached to a secondary pressure adjusting pipe K3 introducing secondary pressure to a low pressure auxiliary governor 3 and performs opening/closing of the pipe K3, a timer T which is connected to the valve V and operates the valve in a closing direction at a midnight time zone and a sub-low pressure auxiliary governor 10 which is connected between the valve V of the pipe K3 and a gas pipe and increases and decreases pilot pressure at a set pressure lower than that of the governor 3 to operate a main governor.
