ABSTRACT:
A valve adapted for installation in a pipe which carries foodstuffs has a housing enclosing a cylindrical bore. At least one opening in the side of the housing provides a radial pipe connection. At least one closure member of segmented cross-section is rotatably disposed in the bore for rotation into open and closed positions with respect to the openings in the side of the housing. A pipe connection is also provided at one end of the housing which opens axially into the bore. The closure member is urged by wedge surfaces radially outwards against the wall of the bore. The closure member is provided above and below the openings for pipe connections in the side of the housing with conical wedge surfaces each coaxial with the longitudinal axis of the bore and diverging away from the opening.
