CONSTITUTION: A ball valve comprises a body(2), a sealing ring(6), and a ball(7). A flow channel(3) is formed in the body. A loading part(14) is into one body formed in the front end of the body. An inclined part(15) is formed contiguously to the loading unit. The inclined part is touched with the front end of the mounting hole of a pipe. An insert(5) is installed in the rear of the sealing ring through a screw part(4). A stem(8) is installed in the upper side of the ball. In the state that a stopper washer(12), a stem nut(10), and a steering wheel(11) are successively coupled in the center of the stem, a nut(9) is fastened to the stem.
