PURPOSE: A pressure setting device for a LNG regulator is provided to manage the set pressure of all safe valves by directly setting the standard pressure of safe valves used for LNG supply. CONSTITUTION: A pressure setting device for a LNG regulator comprises a base(100), a filter part(110), a pilot(130), a gauge(140), a low pressure setting regulator(150), an intermediate pressure setting regulator(160), an outlet valve(170), an output connector(180), a pressure purge connector(190), a second air supply connector(220), a high pressure setting regulator(230), a high pressure output connector(250) and a pressure measurement connector. The base has a sheet form. The filter part is combined in the one upper side of the base. A pilot and a gauge are connected to the filter part. A low pressure setting regulator(150) and an intermediate pressure setting regulator comprise respective intercept valves. The output connector is connected to the outlet valve. The pressure purge connector is connected to the outlet valve and indicates an outlet pressure. The second air supply connector is formed on the upper one side of the base. The high pressure setting regulator is connected to the second air supply connector.
