ABSTRACT:
A shutoff valve for use in a transportation environment has a body with an internal passage and means on the passage wall for attaching the body. There is a chamber in the body in communication with the passage and there is an opening in the body in alignment with the chamber. A seal member is positioned within the chamber and has openings therein in communication with the passage. The body opening is of a size and shape to permit positioning of the seal member within the chamber. There are cooperating means on the seal member and chamber walls fixing the seal within the chamber and preventing rotation of the seal relative to the body. The cooperating means on the seal include air vent openings. A ball member is positioned within and enclosed by the seal member with the ball member being rotatable to open and close the valve. The seal member has an opening slightly smaller than the ball member whereby the seal member is stretched to permit insertion of the ball member, but after such insertion retains the ball member therein. A handle extends through the body and into engagement with the ball member and there is a cover closing the body opening.
