Abstract: A ball valve in which the ball of the valve is positively prevented from blowing out of the valve body in both directions, even if the valve is connected in the wrong direction or the fluid pressure is applied to the valve in the opposite direction. The ball is arranged in a valve body to selectively open and close a fluid passage in the body, and annular seals abut against the ball from both sides of the fluid passage, the annular seals being pushed towards the ball by seal carriers. In one embodiment, one of the seal carriers has a flange on the periphery of one end thereof, and the flange is locked to a step from inside which is formed on inner surface of one end portion of the valve body. In a second embodiment, the ball additionally has two grooves with abutting walls in respective ones of which a spindle and a pin coaxial with the spindle are fitted with the abutting walls positioned on the side of the one seal carrier.

Abstract: A ball valve in which, even when a connecting sleeve is removed by loosening the associated union nut, the ball and annular seals of the valve will not blow out of the valve body under fluid pressure. A ball with an integral spindle is arranged in the valve body in such a manner as to be able to open and close a fluid passage therein. A seat is formed in the valve body and a part of the surface of the ball on the side thereof opposite the side where the spindle is provided and around a rotational axis of the spindle is in surface contact with the seat to thereby pivotally support the ball. Annular seals are provided in the fluid passage abutting against the ball from both sides to pivotally support the ball with the annular seals being urged towards the ball by seal carriers.
