PROBLEM TO BE SOLVED: To provide a ball valve equipped with a steam trap capable of performing functions of not only steam trapping but also a temperature controlling valve. SOLUTION: A ball valve body 2 provided with a T-shaped flow path 6 is rotatably disposed in a casing formed with an inlet 4 and an outlet 5 in a right angle direction, and a temperature actuating element 3 is disposed oppositely to a valve hole 14 formed in a short path of the T-shaped flow path 6. By rotating the ball valve body 2, the inlet 4 and the inlet 5 are united in order of the temperature actuating element 3, the valve hole 14, thereby performing a function as an usual steam strap. By rotating the ball valve body 2, the inlet 4 and the inlet 5 are united in order of the valve hole 14, the temperature actuating element 3, thereby performing a function as a temperature controlling valve discharging only condensate under a prescribed temperature. Furthermore, by rotating the ball valve 2, the inlet 4 or the inlet 5 is blocked with the ball valve body 2, thereby performing a flow path blocking function.
