ABSTRACT:
A valve adapted for installation in a pipe system which carries liquid or paste foodstuffs has a housing enclosing a cylindrical bore. At least one opening in the side of the housing provides a radial pipe connection. Two closure members of segmented cross-section are rotatably disposed in the bore for rotation into open and closed positions with respect to openings in the side of the housing. Cover plates close the opposite ends of the bore and a spindle extends through each plate into the bore. One spindle is connected to one closure member and the other spindle is connected to the other closure member so that the closure members can be rotated independently of each other. 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. The housing is provided with wedge surfaces for cooperating with those on the closure members.
