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.

A shut-off valve comprising: a housing having a cylindrical bore therein; four circumferentially spaced pipe connections radially opening into the housing in a direction substantially perpendicular to said bore; a first closure member in direct sealing contact with the cylindrical bore of the housing to sealingly close off any selected one of said pipe connections; a second closure member, having a construction identical to that of said first closure member, in direct sealing contact with the bore to close off any selected one of said pipe connections; a first upper cover on the upper end of the housing; a second lower cover on the lower end of the housing; a first actuating member extending through the first cover and connected to the first closure member for controlling movement thereof within the bore; and a second actuating member, having a construction identical to that of said first actuating member, extending through the second cover and connected to the second closure member for controlling movement thereof within the bore.
