Abstract

A diverter valve for conveying material to be conveyed, the diverter valve being cleanable using a method for CIP cleaning, comprises a housing with at least three passage openings to feed or discharge the material to be conveyed, the passage openings defining a conveying plane. The diverter valve further comprises a rotary part having an axis of rotation and an outer contour designed conically in relation to the axis of rotation at least in sections, the rotary part being arrangeable in the housing in a sealed manner, the rotary part being displaceable along the axis of rotation in an axially driven manner and being arranged such as to be drivable for rotation about the axis of rotation, the axis of rotation being oriented perpendicular to the conveying plane, a passage duct arranged in the rotary part, which—depending on a rotary position of the rotary part—connects in each case two passage openings for conveying material along the passage duct through the diverter valve. The CIP cleaning method of a diverter valve of this type comprises the pulling back and rotating the rotary part into an intermediate position to clean and then dry the diverter valve intensively.
