The present invention relates to a load-compensating valve for railway vehicles capable of keeping the average air pressure without an extra device to form air pressure with the air supplied from air springs of a railway vehicle; controlling initial pressure and the variation (inclination) of braking pressure when a car is either full or empty; and being set to make braking force corresponding to 80% of the level when the car is empty even when the air springs are damaged. To achieve the purpose, the present invention comprises a body; a first piston included in a first space area formed in an inner side of the body; a second piston included in a second space area formed in a side part of the first space part; a balance beam included in a third space area connecting the first and second space parts in order to deliver virtual pressure of the first piston to the second piston; a main valve included in an upper part of the second space part; a first supply hole connected to an upper part of the second space part; and a second supply hole connected to a side part of the second space part.
