An automatic temperature control valve is provided that the configuration is very simple and usage is convenient, and the manufacturing cost can be saved. An automatic temperature control valve comprises a through-hole(110) which is bored in center and is formed, a valve body consisting of the valve seat(120) forming the stepped projection on the central part of through-hole(100), a fixing ring(220) in which the hot-water vent(221) is formed in the top. An axis hole(211) is formed in the central part into the longitudinal direction. A cap bolt(222) is comprised at the upper part of ball in the central part. A discharge hole(213) bored to the axis hole is formed in outside. A valve seat(212) is formed in the central part of the inside of the axis hole. An axis(210) in which the ball valve(260) and spring(261) are successively formed on the top of the valve seat(212). A shape memory alloy spring(250) is successively formed in the lower part of the fixing ring(220) of the axis into the shape memory alloy. A disc valve(230) includes the packing(231) contacting with each other with the valve seat is comprised in the bottom part. A spring(240) moves the disc valve to the metal material having with elasticity. An on/off valve includes the adjusting nut(241) which is comprised in the end part of the axis and prevents the secession of the spring is formed(200). A connecting member(300) is formed in the lower part of the valve body. A combining member(400) is formed on the top of the valve body.
