Abstract: A liquid sampling valve includes a fixed element having a contact surface and a movable element having a contact surface for contacting the contact surface of the fixed element; the fixed element or the movable element having measuring passageways extending to the contact surfaces, the measuring passageways having an opening for receiving and measuring a liquid sample incorporated into the opening; both the fixed element and the movable element being provided with a plurality of cleaning passageways, each having an opening at a location spaced apart from the central part of the contact surface, the location being different from the locations where the openings for the measuring passageways are provided. Movement of the movable element relative to the fixed element into a first state allows for a liquid sample to be filled into the measuring passageway, and movement into the second state allows for the liquid sample filled in the measuring passageway to be conveyed to out of the element.
