PURPOSE: A quantitative automatic balancing valve is provided to reduce the working time by making the installation of a valve easy, to repair a valve without separation of the valve from a pipe, to reduce the material for manufacturing by compacting structure, and to prevent the damage or deformation due to water hammering by reinforcing rigidity. CONSTITUTION: A quantitative automatic balancing valve(100) has a valve(30) having an inlet(20) and an outlet(22) corresponding to a first body(10) and a second body(20). A support plate having a cartridge installation hole(52) for receiving a cartridge is integrally installed in the second body. Grooves(14,14a,16.16a) formed on both ends of the first body and the second body are connected via a groove coupling(40). Flow rate is automatically controlled by variably installing cartridges. The first body is pre-assembled with the second body before the groove coupling is connected. Thus, assembling and disassembling work is convenient.
