PURPOSE: An automatic temperature control valve is provided to minimize the valve size because an opening/closing housing and an opening/closing disc are elastically installed in the valve body. CONSTITUTION: An automatic temperature control valve(1) comprises an opening/closing housing(3), an opening/closing disc(4), a bias torsion spring(5), a shape memory alloy torsion spring(6), a nut(13), and a cap(7). The opening/closing housing is installed inside a valve body(2) and comprises a plurality of water-feed holes(8). The opening/closing disc comprises a plurality of water-feed holes(9) and axially connected to a shaft(12) formed in the center of the opening/closing housing. The bias torsion spring and the shape memory alloy torsion spring are inserted and assembled to the shaft, with one end fixed to the opening/closing housing and the other end fixed to the opening/closing disc. The nut is screwed to the end of the shaft. The cap is screwed to the valve body.
